1. Introduction What are the ProMark3 and ProMark3 RTK Systems? In this manual, the term “ProMark3” refers to both the ProMark3 and ProMark3 RTK units. When describing a function specific to the ProMark3 RTK, then the term “ProMark3 RTK” is used. ProMark3 is a complete GPS system providing precision surveying in post-processing or real-time, GIS feature collection and navigation. Real-time surveying is only available with ProMark3 RTK.
Real-Time Surveying With a ProMark3 RTK, or after upgrading your ProMark3 into a ProMark3 RTK (see Installing the ProMark3 RTK Firmware on page 267), you can perform real-time RTK surveys. The system will deliver centimeter-accurate positions thanks to Magellan’s new BLADE™ technology. From an L1-only GPS receiver such as the ProMark3, BLADE can deliver RTK accuracies comparable to those of a dual-frequency (L1/L2) receiver.
Items Supplied with ProMark3 The items supplied with ProMark3 are described in the following paragraphs. ProMark3 Receiver Front Panel GPS Receiver includes: • Integrated GPS accurate to sub-meter with WAAS/ EGNOS • Ready for RTCM real-time corrections • Internal antenna.
Side Panel External Antenna Connector Secure Digital Card Slot Door: • Open the door to access the SD card slot I/O Module USB host port (Type A), connect to a USB flash drive, card reader etc. DC Power Input connector 4 Mini USB (Type B) port.
USB Cable The USB cable is used to connect the ProMark3 to an office computer via the ProMark3’s I/O module. Use the mini USB port for this connection and not the USB host port. The mini USB port is located next to the RS232 Sub-D port on the I/O module. Refer to diagrams on page 4. AC Adapter/Charger This device is used to power supply the ProMark3 from the AC power line. If an internal battery has been inserted into the ProMark3 unit, this device will also provide a charging current for the battery.
Vertical Antenna Extension The vertical antenna extension provides clearance for the antenna cable when the antenna is mounted on a tripod. The length is 3 inches (0.0762 m). Field Receiver Bracket The field receiver bracket provides the means for mounting the ProMark3 receiver to the tripod. HI (Height of Instrument) Measurement Tape The HI measurement tape is used to measure height of the GPS antenna over the survey point. The end of the tape hooks onto the antenna.
User Documentation CD This CD includes the ProMark3 Getting Started Guide (4 languages) and the present ProMark3 Reference Manual (English only). Initializer Bar and Antenna Adaptor (Provided with two-receiver systems only.) The initializer bar can be used to initialize your surveys from a base. This 0.20-m bar should be mounted on the base tribrach before use.
ProMark3 RTK Specific Accessories License-Free Radio Modems Radio modems come in pairs, each composed of two similar units that can indifferently be used at the base or the rover. The radio modem used at the base will automatically become a transmitter while the other one, used at the rover, will automatically operate as a receiver. Models. Radio modems come in two different models.
Power/Data Cable. Each radio modem is fitted with a cable for easy connection to the ProMark3. The wiring diagram and pinout are provided below.
Brackets for License-free Radio Modems Each radio modem comes with its own bracket for easy installation on a pole. The radio modem is secured on the bracket using the four screws and washers provided. At the base, the radio modem/bracket assembly should be mounted on the RTK vertical antenna extension so the radio modem and its antenna can easily fit under the GNSS antenna. At the rover, the radio modem/bracket assembly should be fixed on the pole range, just underneath the GNSS antenna.
Additional Items Required but not Supplied For Static Surveys or Base Stations These items allow you to firmly position the GPS antenna over the survey point or station site (see opposite) at a measurable height from the ground. These items (tripod, tribrach and tribrach adapter) are illustrated below.
An option to the tripod, tribrach and tribrach adapter combination is the fixed-height GPS tripod (see below). For Kinematic Surveys An option for mounting the ProMark3 rover when operating in kinematic mode is a range pole (see picture below showing a ProMark3 ready for post-process kinematic surveying).

Post-Process Surveying with ProMark3 The ProMark3 system is designed to perform GPS surveys using static, stop-and-go, and kinematic modes of GPS data collection. The three modes run independently. In the Static data collection mode, the GPS receiver systems simultaneously collect raw data from all available satellites while remaining stationary on their respective points.
The post-processing activity computes vectors (position differences) to determine the position of all observed points relative to one or more fixed point positions. The static data collection method produces the most accurate and reliable results of any mode of GPS data collection. This is due primarily to the extended observation periods required for static data collection.
After data collection is complete, data is downloaded from the GPS receivers to an office computer for post-processing using the GNSS Solutions software. The post-processing activity computes vectors (position differences) to determine the position of all observed points relative to one or more fixed point positions. The Stop-and-Go data collection method is faster than the static method, but not as accurate since the occupation period is much shorter.
Additional GPS receivers are used to locate linear objects such as roads or collect data in a linear fashion for developing topographic elevation data. The recording interval should be set to collect the amount of data needed relative to the speed of travel. A recording interval too long will result in insufficient data. After data collection is complete, data is downloaded from the GPS receivers to an office computer for post-processing using the GNSS Solutions software.
Three different real-time jobs can be performed with the ProMark3 RTK: - Point Logging: RTK positions of points that you visit in turn are logged in a file (a vector file with the “O” prefix). - Kinematic: Logging a trajectory. Each point logged by the system while you are walking along the trajectory will feature centimeter accuracy. The trajectory can be logged either in Time or Distance mode. With the first mode, a new position will be logged every x seconds of time elapsed.
Mobile Mapping with ProMark3 The ProMark3 system is also designed to log GIS features in a job file. GIS features can be of the following types: points, lines, areas and grids. Grid features are Magellan’s specific features detailed in Logging GIS Data on a Preset Grid Feature on page 134. ProMark3 provides in real-time the length of the line you are logging or the surface area of the area you are logging. You don’t need an external antenna or any other accessories to collect GIS jobs.
After making these two choices you can start logging your GIS features in the open job. The navigation screens may be helpful to guide you to the features you have to go to.
Navigating with ProMark3 The ProMark3 includes a wide range of navigational capabilities that you will find useful in your day-to-day surveying and mobile mapping operations. Two useful navigation features are: • The map screen can be utilized to help you find a project site. • The ProMark3 serves as an excellent reconnaissance tool. You can enter the known coordinates of the feature you wish to reckon as a waypoint, and use ProMark3 to navigate to within 3 meters (10 feet) of the feature in the field.
Time Spent in The Field Post-Processing In general, the amount of time required to occupy a point depends on several factors: 1. Distance between survey points. In general, the greater this distance, the longer the observation time. 2. Environmental conditions, or the amount of obstruction or canopy preventing a completely open sky view. Some obstructions may block the reception of the satellite signal, requiring longer observation times to collect additional data for accurate processing.
Kinematic The Kinematic method also requires an initialization as detailed in the Stop-and-Go method. Kinematic data collection does not use an occupation timer since kinematic data is collected while moving. The recording interval must be set to a value that properly matches the speed you are moving. A recording interval set too slow may result in data that does not represent the feature being surveyed.
Mobile Mapping The ProMark3 needs 2 or 3 seconds to open a feature, record at least one epoch and close the file successfully. So when you open a point feature, please record for 2 or 3 seconds before closing the feature. To improve accuracy of point features, we recommend recording for 30 seconds - or even longer for optimal accuracy.
2. Preparing For First-Time Use Charging the ProMark3 Battery Pack Battery Life Whether used as a rover or a base, ProMark3 will run for 8 hours with its internal battery in typical conditions of use. The ProMark3 includes a rechargeable, replaceable battery pack. Before using the receiver, you must first charge the battery pack: 1. Locate the removable battery provided. 2. Open the battery door, located in the back of the receiver, using a screwdriver or a coin. 3.
7. To detach the clip-on I/O module, press the release button on the module. Turning On/Off the Receiver ProMark3 Start-up Screen Once you have charged the battery, press the red key (the power key) on the front of the receiver until the power indicator turns solid green. You will first see the receiver’s start-up screen (see opposite left). Wait for the progress bar to complete its sequence. The screen then displays the ProMark3 workspace with its main icons (see opposite right).
Calibrating the Screen For the first-time use, you need to align your display screen so the cursor on the touch screen align with the tip of your stylus. Use the stylus pen to tap the center of each target that appears on the Calibration screen with the tip of the stylus. Tap anywhere on the display when finished. To re-calibrate your screen at anytime, double-tap the Settings icon then double-tap Stylus from the list, tap the Calibration tab and then follow the instructions.
Initializing GPS Please Go Outside to Perform Initialization! Initialization is required when 1) the receiver is brand new, 2) you have moved more than 500 miles from the last place you were using it, 3) memory has been completely erased or 4) the receiver has not been used for more than a few months. Take the receiver to a location where there is a clear view of the sky, then: - From the ProMark3 workspace, tap successively the Utilities icon and then the GPSInit icon.
Preliminary Settings From the ProMark3 workspace, do the following: • Double-tap the Surveying icon if you want to perform a real-time (ProMark3 RTK only) or post-processing survey. • Or double-tap the Mobile Mapping icon if you want to perform a GIS job. Whatever your choice, ProMark3 will then display a navigation screen. Just press the NAV or ESC button to scroll through the different available navigation screens. For more information on Navigation screens, please refer to Navigation on page 143.
Entering the Receiver ID (From within Surveying function only) The Receiver ID screen provides you with the ability to enter the 4-character receiver ID which is used in naming the raw data files. Each raw data file from this receiver will include this 4-character receiver ID. Specifying the Antenna Used You select this option to define the type of external antenna used. Three different types of antennas are listed (ProMark Antenna 110454, NAP100 or Other).
Checking that ProMark3 Receives Satellites Press NAV repeatedly until the Satellite Status screen is displayed. This screen shows which satellites the receiver is tracking and where they are located in the sky. If you are not tracking 3 or more satellites you may have to move to a more open area. When used with its internal antenna (Mobile Mapping only), the receiver will have the best view of the sky when you hold it at an angle of 45 degrees from horizontal and not too close to you.
3. RTK Setup Introduction to RTK Enabling the RTK algorithm in the ProMark3 RTK is simply done by launching “Surveying”, pressing MENU, selecting Receiver Mode and then Real-Time or Real-Time & Raw Data Recording. From this time on, the ProMark3 RTK will operate to deliver fixed position solutions, provided the operating requirements are met. Selecting Real-Time & Raw Data Recording is a safe way to perform a real-time survey.
4. ProMark3 RTK Configurations Base Radio Data Link Rover Rover Internet Base/Rover (Base/rover System) GPRS Data Link Rover-Only (Network Connection) + Cell Phone 5. Rover Initialization. Before starting a survey, the rover must be initialized. There are four possible methods: “On The Fly”, “Static”, “Known Point” and “Bar”. The “Bar” method can only be used if you have your own base. Three of the initialization methods are introduced in the post-processing chapter (see page 98).
Base/Rover Configuration You are using your own ProMark3 RTK base to generate the RTCM corrections needed by the rover. A pair of Magellan license-free, plug-and-play radios is used for the data link. About the Base Position In addition to the good reception conditions required at the base (see page 37), you must also think about whether the base position should accurately be known with great precision or not. The explanations below will help you understand what you need in terms of base position accuracy.
Setting Up the Base The installation site should offer the best possible GPS reception conditions. The antenna should have a clear view of the sky in all directions. There should be no, or a minimum of satellite obstructions in the vicinity. Setup with Kinematic Bar 5. 8. 4. 7. 12. 3. H Slant 6. 2. Setup without the Kinematic Bar 9. 1. 10. H Vertical 11. 5. 1. Set up the tripod / tribrach combination over the point. 2. Screw the RTK vertical antenna extension into the tribrach. 3.
The higher the radio, the better the quality and range of the radio link. Warning! Unscrewing the radio antenna protection is pointless or even hazardous for the antenna. 38 6. Secure the radio bracket onto the RTK vertical antenna extension. Place it as high as possible, just underneath the GNSS antenna, as shown. Placing the radio too low will reduce the radio range. 7. Connect the external antenna cable to the GNSS antenna. 8. Connect the other end of the external antenna cable to the ProMark3 RTK.
Configuring the Base 1. Double-tap the Surveying icon. 2. Press MENU, tap Receiver Mode, then Real-Time. 3. Press MENU, tap Base Station and then enter the base parameters: • Station ID: Enter a 4-character string (0.. 4095) for an unambiguous identification of this base. • Height Type: Indicate the type of height (Slant or Vertical) you measured while setting up the base ( see step 12 on page 38). • Antenna Height: Enter the height you measured while setting up the base (see step 12 on page 38).
NOTE: Control points uploaded to ProMark3 RTK have always their coordinates converted to WGS84. When you select a control point for use as the base position, these coordinates are again converted, this time to the coordinate system (see page 237) and map datum (see page 238) used in the ProMark3. The converted coordinates are displayed in the Location and Elevation fields. • Manual entry: Tap successively inside the Location and Elevation fields and enter the known coordinates.
Setting Up the Rover 5 6 7 H Slant H Vertical Install the unit on its range pole: 1 1. Mount the GNSS antenna on top of the pole. For a “Bar” initialization, use a quick release extension so you can easily move the antenna between 2-3 the kinematic bar and the range pole. For the other initialization methods, there is no such requirement. 2. Mount the radio modem onto its 4 bracket using the screws, nuts and washers provided. 8 3. Secure the radio bracket onto the pole. 6-7 4.
Configuring the Rover 1. Turn on the ProMark3 RTK. 2. Double-tap the DGPS Configuration icon. This opens the DGPS Configuration window. 3. Tap Select Mode, select UHF and tap OK. Tap OK again to close the DGPS Configuration window. Initializing the Rover 1. For a “Bar” initialization, move the rover antenna from the range pole to the kinematic bar (see picture right). For all other initialization methods, skip step 1. 2. On rover side, double-tap the Surveying icon. 3.
• Known Point: The rover antenna, placed over a known point, should not be moved until initialization is achieved. If you choose this option, the receiver will first ask you to indicate the name of the control point from which you initialize the rover. Select a point from the prompted list. The initialization screen is then displayed (see screen example in the left column). Skip to step 6. Warning! This method will be successful only if the antenna height has already been entered.
7. Tap OK to close the Initialization window. 8. For a bar initialization, move the rover antenna from the initializer bar to the top of the rover pole (see picture below right). While doing this, take care not to mask the rover antenna or else you would have to resume initialization. For all the other initialization methods, skip step 8. 9. Refer to Standard RTK: “Surveying” on page 51 to start your survey.
Rover-Only Configuration (Network) Two types of connections are possible: NTRIP and Direct IP. Both rely on the use of a Bluetooth-enabled, GPRS-enabled cell phone within range of the ProMark3 RTK. No user-owned base needs to be deployed in this configuration. The “Rover-Only” Configuration requires that you establish a Bluetooth link to your cell phone and then a GPRS connection from the ProMark3 RTK via the Bluetooth link and the cell phone.
Configuring the Rover in NTRIP Mode 1. 2. 3. 4. Turn on the ProMark3 RTK. Double-tap the DGPS Configuration icon. Tap the Select Mode button. Select NTRIP and then tap OK. This gives access to the NTRIP settings window from which you can now do the following: a) Establish a Bluetooth connection with your cell phone. b) Establish an Internet connection via the cell phone. c) Gain access to the NTRIP provider via the cell phone and download the provider’s NTRIP source table. 5.
6. To establish a GPRS connection to the Internet via the cell phone: For step 6, you need to know the GPRS call number as well as your GPRS connection profile (user name, password, domain). Please ask your phone operator and/or GPRS provider if you don’t know these parameters. • Tap on the NTRIP Settings window. • In the window that opens, double-tap the Make New Connection icon.
7. To choose a station from which to receive RTCM corrections: For step 7, you need to know your NTRIP connection profile (host, port, login, password). Please contact your NTRIP provider if you don’t know these parameters. • Tap on the NTRIP Settings window. The NtripCaster Connection window opens in which you can store several NTRIP configurations.
Configuring the Rover in Direct IP mode 1. 2. 3. 4. Turn on the ProMark3 RTK. Double-tap the DGPS Configuration icon. Tap the Select Mode button. Select Direct IP and then tap OK. This gives access to the Direct IP settings window from which you can now do the following: a) Establish a Bluetooth connection with your cell phone. b) Establish an Internet connection via the cell phone. c) Enter the IP address from which corrections can be obtained. 5.
Initializing the Rover The initialization phase is similar to that described for a base/ rover configuration (see page 42). The only difference is that you cannot initialize the rover using a kinematic bar since the base is not your property.
4. Standard RTK: “Surveying” It is assumed that RTK has been implemented according to the instructions provided in chapter RTK Setup on page 34. Once the rover has been initialized (see page 42 or page 49, depending on whether you are in base/rover or rover-only configuration), you can move on to the survey as such. Always take care to maintain maximum satellite visibility from the antenna in order to preserve system initialization.
3. Tap the OK button. This opens a new screen on which you can see the following parameters: • The name of the opened log file is shown in the title bar between brackets. • Baseline: Baseline length in km (distance between base and rover). • Solution: Solution status. Check that it is “Fixed” for centimeter accuracy. • Receiver status: SV: Number of received SVs. Should be 6 or more. PDOP: Should be less than 3. Age: Age of corrections (should not be greater than 2 sec).
6. Move to the next point you want to log. 7. Resume steps 3 through 6 as many times as necessary. 8. When all points have been logged, tap DONE on the screen. This closes the open log file, which now contains the positions of all the logged points, and takes you back to the last displayed navigation screen. Logging Trajectories in Real Time 1. Walk to the start point of the trajectory and stand still on that point. 2.
3. Tap the OK button. This opens a new screen on which you can see the following parameters: • The name of the opened log file is shown in the title bar between brackets. • Baseline: Baseline length • Solution: Solution status. Check that is “Fixed” (for centimeter accuracy). • Receiver status: SV: Number of received SVs. Should be 6 or more. PDOP: Should be less than 3. Age: Age of corrections (should not be greater than 2 sec). HRMS and VRMS: Should be in the order of 0.03 meters (0.
Staking Out It is assumed that the rover has already been RTK initialized. 1. Press the LOG key and then enter the following parameters: • Survey Mode: Select Stakeout. • Antenna Height: Enter the height you measured in the setup phase (see page 41). ProMark3 RTK will save and indefinitely use this value until you change it manually. • Units: Specify the unit that was used to measure the antenna height (meters, US feet or Int feet).
3. After you have selected a point from the list or entered coordinates manually, the ProMark3 RTK switches to the compass screen. The arrow indicates the direction in which you are currently walking and the symbol indicates the direction to the stakeout point. 4. Change direction, and walk slowly, in order to align the arrow with the stakeout point. When you walk in the right direction, you’ll see that the arrow is vertical and the stakeout point at the top of the compass.
To save the as-staked position: • Tap the OK button. This opens a new screen on which you can now see the Remain field count down. In the window’s title bar is the name of the log file where the position is about to be saved. Note that a non-editable Site ID, different from the name of the target point, is automatically assigned to that position. GNSS Solutions will automatically make the correspondence between the target point and the saved position.
5. Advanced RTK: FAST Survey Option Introduction The two requirements for running FAST Survey are: 1) You are using a ProMark3 RTK and 2) FAST Survey has been unlocked. This section focuses on three basic functions: Store Points, Stakeout Points and Localization. Note also that the functions supported by FAST Survey to control conventional systems are not discussed in this section. For more information on these functions, please refer to the FAST Survey Reference Manual provided on CD-ROM.
MENU Screen This screen shows five different tabs giving access to the main functions of FAST Survey. Although all function titles on each tab are self-explanatory, a more detailed definition of these functions is provided below. The right arrow located in the upper-right corner of the MENU screen allows you to access the MAP screen (see page 63). File tab Job: Allows you to select an existing coordinate file for your job or to create a new coordinate file. A job consists of real-time data only.
Equip tab Rover Equip Tab Instrument: Allows you to set the equipment type that you will be using (ProMark3 Base or ProMark3 Rover). If Instrument=ProMark3 Rover, the three buttons that follow are the following: Rover Settings: Used to set the rover receiver to the correct parameters and to instruct the receiver that it is a rover. DGPS Configuration: Runs the DGPS Configuration utility through which UHF, Beacon, NTRIP or Direct IP configurations can be implemented.
Surv tab Store Points: Principal data collection routine (gives access to the Point Logging function) Stakeout Points: Allows you to stakeout to a selected point by guiding you to the point with a series of commands and directions (Point Stakeout function) Stakeout Line/Arc: Opens a secondary dialog where you can choose between Stake Line, Stake Centerline, Stake Arc (3 points) and Stake Arc (PC, R, PT) Offset Stakeout: Will stake out up to 2 user defined horizontal offsets to a centerline at any station as
COGO tab Keyboard Input: Allows you to manually enter or edit coordinates in the current job file or the current control file. Inverse: Reports the bearing and horizontal distance between any two user specified points that are contained within the current job. Areas: Calculates the area of a closed figure that is defined internally by user-entered point numbers contained within the current job or by a polyline picked from the screen.
: This icon, located at the top of the MENU screen, indicates the type of survey equipment selected (GPS or Conventional). Clicking on this icon allows you to access the Instrument window (see opposite) in which you may either save the current FAST Survey configuration or recall a previous one. Clicking on the Current tab allows you indentify the survey equipement (Type, firmware version, etc.).
Getting Started With FAST Survey Creating a New Job FAST Survey first asks you to open a job (a crd file). Do the following: 1. Choose Select New/Existing Job. A new screen is now displayed. 2. In the Name field, type in the name of the job you wish to create. For example, type in “tuto1.crd”. 3. Then tap OK to create the job. The screen then displays the Units tab. 4. On the Units tab, set the desired units and parameters for the job. 5. Tap on the GPS tab.
Configuring a Base It is assumed that the ProMark3 RTK base has been set up as explained in RTK Setup on page 34. If you want to use the Bar method to initialize the rover, don’t forget the kinematic bar between the antenna and the tribrach. Before running FAST Survey, run the DGPS Configuration utility, tap Select Mode, choose UHF and tap OK twice to close DGPS Configuration. This is to make sure the serial line between the radio and the ProMark3 RTK is properly configured. 1.
Configuring a Rover It is assumed that the ProMark3 RTK rover has been set up as explained in RTK Setup on page 34. Tap on the Equip tab. Tap the on the Instrument button. Select ProMark3 Magellan Rover and tap OK. Tap on the Rover Settings button, define the antenna height and type as well as the elevation mask. Indicate the type of position solution that is expected from the rover (“Float” or “Fixed” status).
Localization This operating mode is used in the following cases: - The coordinate system is unknown or its characteristics are not accurate enough. - The base station is operated on a reference point whose position was only determined in autonomous GPS mode. - A local coordinate system is used for field operations. In either of these three cases, you will have to localize your system before starting your job, using control points.
Click on the button to access the list of points available from the open job. Click OK after selecting a point from the list. A new screen then appears asking you to enter the true coordinates of the point. There are three different methods for entering these coordinates (see screen opposite): 1. They can be read from the rover receiver. In this case, the rover should be positioned over the concerned control point. 2. They can be entered manually (WGS84 coordinates). 3.
Logging RTK Points 1. Tap on the Surv tab and then on Store Points. The screen now displayed allows you to log all your points. The figure below summarizes all the functions available from that screen.
6. After logging all your points, tap MENU in the upper-right corner of the screen to return to the menu. Logging RTK Points in Continuous Mode 1. On the Surv tab, select the Auto by Interval function. Two different modes are possible: Time or Distance. 2. If you choose Distance, enter the horizontal and vertical increment value respectively in the X/Y and Z fields, according to the chosen unit. If you choose Time, enter the increment value, in seconds. 3. Enter a point Id.
Tap the X button again (changed into a right arrow during pause) to resume data logging in continuous mode. If you come back to the main menu by tapping on MENU, then data logging in continuous mode is automatically stopped. Staking out RTK Points 1. Tap on the Surv tab and then select Stakeout Points. The screen now displayed allows you to stake out your points. 2. On this screen, FAST Survey asks you to choose the point you want to stake out.
3.
The number of measurements will depend on the value entered earlier through the File tab>Configure Readings function. Once the position has been determined, FAST Survey displays the results of the computation so that you can check them (see below right). 5. Tap OK if you are satisfied with the results. FAST Survey will then save these results and will take you back to the stakeout screen for the next point. Downloading Land Survey Projects See Downloading RTK Data Collected With FAST Survey on page 169.
6. Post-Processing Surveying This chapter presents step-by-step procedures for performing a GPS survey with the ProMark3 system. Review this chapter thoroughly before attempting to perform your first survey. As an exercise, take your system outside of your office and perform a sample survey following the procedures outlined below. Then download and process the collected data with GNSS Solutions. After this exercise, you will be ready to perform your first real survey with the ProMark3 system.
As an illustration, consider an example where two new intervisible points are to be established on a project site for use as control for a boundary survey. The two new points need to be tied to an existing control point 3 kilometers (1.9 miles) away. Three-Point Control Survey Example If you were to perform this survey with a conventional total station, you would probably plan on running a closed-loop traverse from the existing control point through the two new points (see figure below).
The previous example resulted in a very simple network design. The figure below represents a more complex control survey where 10 new points are to be established based on 2 existing horizontal and 3 existing vertical control points. 15-Point Control Survey Example Again, if you were to perform this survey with a conventional total station, you would design a traverse plan which produced a strong looking network of closed-loop traverses through the points of the survey.
When designing your network, keep the following principles in mind: • Design loops through the network points which resemble a square or circle. Avoid loops that are long and skinny. Circular or square shaped loops are stronger geometrically. • Keep the number of points in each loop fewer than 10. • Always include a direct link between intervisible points, i.e. points which may be used as a pair for orientation of a conventional traverse.
If you are in luck, the area is relatively flat and there is a straight road running from the existing control point to the two new points to be established, thus minimizing the number of legs required to complete the loop. Surveying with GPS has the advantage of not requiring line-ofsight between the points surveyed. This allows for direct observations between the points. To illustrate this, let’s take our 3-point control survey network design, shown again below.
Now consider the situation where a 3-receiver ProMark3 system is used. By placing one receiver on each of the 3 points in our network, the data for all three vectors can be collected in one observation, rather than the 3 separate observations required with using a 2-receiver system. Now consider the observation plan for the more complex 15point survey, shown again below.
Now consider the situation where the 15-point control survey above is to be performed using a 3-receiver ProMark3 system. With 3 receivers, each observation session will produce 2 vectors from the network design. For example, you may start by placing one receiver on point 1, the second on point 2, and the third on point 7. These three receivers would simultaneously collect data on these three points, resulting in the vectors between points 1 and 2, and points 1 and 7.
Notice that all observation sessions, except for session 6, produce 2 vectors required from the network design. Observation 6 produces only one since there were an odd number of required vectors (19). This completes the discussion on how to execute the observation plan. The next question to answer is “When do we perform the observations?” The best time to perform GPS surveys is determined by an examination of the GPS satellite constellation at your location for a given time of day.
You provide the software with your current location and the date when you wish to perform your survey. The software then provides you with multiple ways of examining the satellite constellation at your location for the given time. Pay particular attention to satellite availability (number of satellites in view) and the satellite distribution. To assist in analyzing the quality of satellite distribution, Dilution of Precision (DOP) values are presented.
The ProMark3 receiver includes a feature which estimates the observation time required to produce a quality solution. This feature is called the “Observation Range” and is discussed in more detail later on in this chapter. The Observation Range (or Observation Timer) takes into account satellite availability and distribution when determining the required observation time.
Running a Static Survey The procedures for performing a static survey with the ProMark3 system can be broken down into five primary categories: equipment check, site selection, system setup, static survey setup and data collection. Following the steps presented below should result in successful execution of your GPS survey. Note: Remember that data must be simultaneously collected between 2 or more ProMark3 receiver systems in order to produce vectors between the receivers.
Equipment Check Prior to leaving the office to perform your survey, be sure to perform a thorough check of your GPS equipment: 1. Check through the ProMark3 system to ensure all components are present to successfully perform the survey. 2. Check to ensure that you have sufficient battery power to complete the survey. Bring along a spare set of batteries for insurance. 3. Bring along a copy of your network design and printout of the satellite availability and distribution analysis.
For the same reason, GPS cannot be used in tunnels or under water. Other objects such as trees will partially obstruct or reflect/refract the signal; reception of GPS signals is thus very difficult in a heavily forested area. In some cases, enough signal can be observed to compute a rough position. But in virtually every case, the signal is not clean enough to produce centimeter-level positions. Therefore, GPS is not effective in the forest.
You may need to determine the position of an existing point where, obviously, the location is not debatable. In situations were an existing point is in a heavily obstructed area, you may be forced to establish a new point offset from the existing point, or preferably a pair of intervisible points, and conventionally traverse to the required point to establish its position. Be aware that obstructions at a GPS data collection site will affect the observation time required to accurately determine its location.
System Setup (Base and Rover) Now that the survey site is identified, it is time to set up the ProMark3 receiver system over the point to be surveyed. The setup procedure is illustrated below. 2. 7. 4. 6. 3. 5. H Vertical H Slant 1. Typical setup with tripod is described here. You can also use a fixed-height tripod. 88 1. Set up the tripod / tribrach combination over the survey point. This is done in precisely the same manner as for a conventional total station.
2. Attach the vertical extension bar and a tribrach adapter to the GPS antenna. With the GPS antenna in hand, attach the included vertical extension bar to the 5/8-11 thread on the bottom of the antenna. Attach a tribrach adapter to the other end of the vertical extension bar. If using a fixed-height GPS tripod rather than a conventional tripod, a tribrach adapter is not required 3. Place the GPS antenna assembly on the tripod. Be careful not to disturb the tripod when mounting the antenna assembly. 4.
Static Survey Setup (Base and Rover) 1. Turn on the receiver by pressing the red key. Wait for the ProMark3 workspace to appear on the screen. 2. Double-tap the Surveying icon to run the Surveying function. The screen displays the navigation screen that was last displayed. 3. Make the settings required when first using the Surveying function: • Press the MENU key • Tap Setup. In the Setup menu, tap successively the options you need to set.
You must assign a unique site ID to each point surveyed. 6. Enter the following parameters: • Site ID: Tap inside the field and enter a 4-character string using the virtual (on-screen) or real keyboard. on the onThen press the ENTER key, or tap screen keyboard, to validate the site ID. • Survey Mode: For a static survey, tap the currently selected mode and then tap Static. • Site Description: (Optional) Tap inside the field and enter a narrative description of the point (20 characters max.).
Slant Vertical • Height Type: Tap inside this field and then tap the method used to measure the antenna height: Slant if you measured the antenna height to the outside edge of the GPS antenna, or Vertical if you measured the antenna height to the bottom of the GPS antenna mounting thread (see opposite). • Recording Interval: Tap inside this field and then tap the recording interval (time in seconds between any two consecutive acquisitions of GPS data) you wish to use in your static survey.
The Static Survey screen opens providing information on the status of your survey during the data collection period. With an antenna that has the best possible view of the sky, you should have #Sats continuously greater than 4 and PDOP continuously less than 4. Obs. Range is equivalent to Obs. Timer in ProMark2. Information provided here will help you determine when enough data has been collected. • Obs.
• # Sats: Displays the current number of healthy satellites – seen above the elevation mask – being logged into memory. • PDOP: Displays the PDOP value at any given time, computed from all observed healthy satellites above the elevation mask. • Site ID: Reminds you of the name you have given to the point you are surveying. • File Name: Indicates the name of the file in which data is being collected. The file is automatically named by the receiver according to conventions provided in Appendices on page 262.
Introduction to Kinematic Surveying The kinematic data collection process requires at least two receivers collecting data simultaneously. One receiver is called the base and must remain stationary throughout the data collection. Typically, the base receiver will occupy a survey point for which the precise position is already known. Once operational, the base system simply collects and stores raw data from all satellites with line of sight to the GPS antenna (cf. Static survey).
It is highly recommended that a pole with bipod legs be used for Stop-and-go data collection to insure that the antenna is stable during this data collection period. Once the point occupation is finished the system can be carried to the next survey point and the procedure is repeated. Kinematic Continuous kinematic data collection is suited for collecting bulk points with minimal attributing (terrain modelling) or linear features such as a road centerline.
During the kinematic data collection, the receiver must maintain lock on at least 5 satellites which are common at both the base and rover stations. If the receiver detects that less than 5 satellites are tracked, it will send out an alarm indicating that the system must be re-initialized. In cases of loss of lock due to obstructions, it is possible that the accuracy of processed results will be degraded if re-initialization is not performed in the field.
Initialization Methods The initialization phase is required to ensure that your kinematic surveys, whether continuous or Stop & Go, will reach centimeter-level accuracies through post-processing. With the “Known” method, you can make a survey at a fairly long distance from the base. Three possible methods, from fastest to slowest: • Known: Initialization on Known point.
“Known” point means a point that is stored in the receiver’s memory as a control point. With the “Known” initialization method, the total duration of the survey required for a successful survey increases with the distance from the rover to the base. Running a “Stop & Go” Survey Base Setup and Operation Allowing for kinematic initialization using Initializer bar at the base The base is setup and operated in the same way as it is in static surveys (see page 88).
Rover Setup Install the unit on its range pole: 1. Attach the field bracket onto the pole. 2. Place the ProMark3 receiver into the field bracket. 3. Connect the GPS antenna cable to the unit. 4. Mount the GPS antenna on top of the pole or, in the case of a bar initialization, at the end of the base’s initializer bar. 5. Connect the other end of the antenna cable to the rover antenna. 1. Temporary Setup for Bar Initialization: 2.
Satellite Status screen Initialization method: 1) None 2. Double-tap the Surveying icon to run the Surveying function. The screen displays the navigation screen that was last displayed. 3. Make the settings required when first using the Surveying function: • Press the MENU key • Tap Setup. In the Setup menu, tap successively the options you need to set. Remember you need to define the Storage medium (internal memory or SD card) and the Receiver ID.
Slant 102 Vertical Enter the following parameters: • Site ID and Site Description: Set these two parameters after choosing the Initialization method (see below after the Initialize parameter). • Antenna Height: Tap inside this field and enter the vertical distance between the antenna and the surveyed point. Be careful when entering the antenna height as this field uses a fixed format (xx.xxx). Then press the on the on-screen keyboard, to ENTER key, or tap validate the content of this field.
Carefully choose the Site ID! Remember ProMark3 will automatically increment the Site ID as you progress in your Stop-and-go survey. So make sure the Site ID you choose will not generate Site IDs that already exist. If that was the case, ProMark3 would overwrite these Site IDs without warning you. • Site ID: Set this parameter according to the initialization method you choose: - If or Bar is selected, you can freely enter a Site ID from the keyboard.
• Control Point check box: Displayed only if is selected in the Initialize field. If you check this box, you will be able, later on, to use the start point -i.e. the point where initialization took place- as a control point. Initialization Phase Initialization count-down. 104 7. Tap the Log button at the bottom of the screen. This starts data collection which will stop only at the end of the Stop & Go survey.
If you are performing initialization on bar, you now have to move the rover antenna from the initializer bar to the top of the rover pole (see illustration opposite). While doing this, take care not to mask the rover antenna or else you would have to resume the initialization. • With selected, because there is no initialization phase, ProMark3 directly switches to data collection. Continued in next chapter Data Collection. Data Collection 8.
In this case, press the LOG key, which here is different from tapping the on-screen Log button, and then review and correct if necessary the following parameters: - Site ID: Enter a name for the 1st point to be surveyed - Site Description: (Optional) Tap inside the field and enter a narrative description of the point (20 characters max.). Then press the ENTER key, or tap on the on-screen keyboard, to validate the content of this field.
10.While holding the antenna pole stationary above this point, tap Log on the screen. The receiver then displays the screen below. Make sure the rover antenna has the best possible view of the sky at all times during the survey. This should result in #Sats continuously greater than 4 and PDOP continuously less than 4. The Obs. Range field is irrelevant to the Stop & Go mode and for this reason is left blank. You may shorten the static occupation time (i.e.
• PDOP: Displays the PDOP value at any given time, computed from all observed healthy satellites above the elevation mask. • Site ID: Reminds you of the name given to the point you are surveying. • File Name: Indicates the name of the file in which data is being collected. The file is automatically named by the receiver according to conventions provided in Appendices on page 262. • Current Power and Memory statuses in graphical form. 11.Wait until Remain = 00:00:00.

Note that the content of the Site ID field is incremented by 1 after ending static occupation on a point (increment: 0 to 9, then A to Z, then 0.. again, etc.). You can however change the Site ID between any two occupation times by pressing the LOG key (not the on-screen LOG button) and editing the Site ID field. 12.
Rover Setup Install the unit on its range pole: 1. Attach the field bracket onto the pole. 2. Place the ProMark3 receiver into the field bracket. 3. Connect the GPS antenna cable to the unit. 4. Mount the GPS antenna on top of the pole or, in the case of a bar initialization, at the end of the base’s initializer bar. 5. Connect the other end of the antenna cable to the rover antenna. 6. Measure the antenna height. 1. Temporary Setup for Bar Initialization: 2.
Satellite Status screen Initialization method: 1) None 2. Double-tap the Surveying icon to run the Surveying function. The screen displays the navigation screen that was last displayed. 3. Make the settings required when first using the Surveying function: • Press the MENU key • Tap Setup. In the Setup menu, tap successively the options you need to set. Remember you need to define the Storage medium (internal memory or SD card) and the Receiver ID.
Slant 112 Vertical Enter the following parameters: • Site ID and Site Description: Set these two parameters after choosing the Initialization method (see below after the Initialize parameter). • Antenna Height: Tap inside this field and enter the vertical distance between the antenna and the surveyed point. Be careful when entering the antenna height as this field uses a fixed format (xx.xxx). Then press the on the on-screen keyboard, to ENTER key, or tap validate the content of this field.
Carefully choose the Site ID! Remember ProMark3 will automatically increment the Site ID as you progress in your Kinematic survey. So make sure the Site ID you choose will not generate Site IDs that already exist. If that was the case, ProMark3 would overwrite these Site IDs without warning you. • Site ID: Set this parameter according to the initialization method you choose: -If or Bar is selected, you can freely enter a Site ID from the keyboard.
Initialization count-down. What happens after starting data collection depends on the chosen initialization method: • With Bar or Known selected, the receiver first goes through an intermediate screen showing the countingdown of the initialization phase (see screen opposite). The Remain field will count down beginning from the value of the Time on site field set in the Survey Settings screen. At the end of the countdown sequence, the Remain field reads “00:00:00”.
Data Collection 8. Walk to the start point of the trajectory you want to survey, making sure you will not mask the antenna. 9. If you have initialized on bar or known point, you may need to change some of the survey settings (typically you need to change the antenna height after moving the rover antenna from the initializer bar to the pole).
Information provided here will help you monitor the survey of the trajectory. • Obs. Range (Observation Range): Field left blank as it is irrelevant to Kinemativ survey. • Elapsed: Displays the time elapsed, in hours, minutes, seconds, since you tapped the Log button (at the begginning of the trajectrory). • # Sats: Displays the current number of healthy satellites – seen above the elevation mask – being logged into memory.
Log 0001... Rover 00014... 0015... Pause Log 0028 Bold lines indicate the trajectories surveyed. Data collection is NOT suspended between the trajectories. 11.Use the buttons at the bottom of the screen to do the following: • Pause: Tap this button when you arrive at the end of the trajectory. Remember tapping this button does not mean that you stop data collection: actually data collection continues! When you tap Pause, the button is then renamed “Log”.
Re-Initialization When is Re-Initialization Required? Re-initialization is required when the following message appears on the screen, due to poor GPS reception, while you are running a Stop & Go or Kinematic survey that you initialized through the “Bar” or “Known” initialization method: When this occurs, you will unfortunately have to resume all or part of your survey.
Preventive Steps to Facilitate Re-initialization If you take care to create “intermediate” control points as you are progressing in your stop-and-go surveys, you will make reinitialization easier in the sense that you will not have to resume the survey from the beginning. Instead, you will just have to walk back to the last “intermediate” control point you will have surveyed and run a new initialization on this point using the “Known” option.
2. Re-initializing on an intermediate control point If the “Loss of Lock. Reinitialize” message arises when you are performing a Stop & Go survey: • Acknowledge the alarm by tapping anywhere outside of the message window. • Walk to the control point you last surveyed. • Check that you have enough satellites and a good PDOP on that point • Press the LOG key. • Select “Known” in the Initialize field, then tap the Site ID corresponding to this point (remember in our example you named that point“CP10”).
• Select “Kinematic” as the Survey mode • Select “Known” in the Initialize field, then tap the Site ID corresponding to the “intermediate” control point (remember in our example you named that point “CP10”). • Tap Log and wait for the Remain field to countdown to zero. • Walk to the beginning of the trajectory you were surveying when the alarm message occurred. • Press the LOG key, rename the Site ID. • Tap Log to resume the survey of the trajectory you have not been able to complete the first time.
7. Mobile Mapping Feature Libraries A feature library is a hierarchical structure that guides you through the description process so you know you will describe thoroughly and quickly each feature you visit.
You can upload as many feature libraries as you want into ProMark3. Just remember that you can use only one feature library for logging data to an individual job. Logging New GPS/GIS Data Remember you can use the real-time DGPS capability if you need it. See Selecting a DGPS Mode on page 209. With a ProMark3 RTK using an external antenna, MobileMapping can also be run in RTK mode, thus offering the same accuracy level as in surveying.
1. Creating a Job and Selecting a Feature Library - Press the LOG button - Tap Create New Job. The screen displays the Job Name field in which you should enter the name of the new job. A keyboard is displayed underneath to let you enter this name. To enter a name, tap on the corresponding letters on the keyboard. Entering a job name Note that each ProMark3 includes a "Generic" library containing default features. This library contains a point feature, a line feature, an area feature and a grid feature.
ProMark3 uses a fixed, time-based logging interval (1 second) when you log a point feature. The logging interval parameter cannot be accessed when you log a point feature. Logging screen The Logging screen also displays the time elapsed since you started logging at this point feature, the number of satellites currently received and the current value of PDOP (see also page 139).
3. Logging and Describing a Line Feature Basically, you use the same procedure as when you log a point feature (see 2. above). There are however two differences when you log a line feature: - You need to define a logging interval when you start logging the feature - And then you are supposed to move from the beginning to the end of the line feature before stopping the logging. These differences are explained below.
Logging screen The Logging screen also displays the distance traveled since you started logging the line feature, the number of satellites currently received and the current value of PDOP (see also page 225). Two options are then prompted: By Time: Select this option when you want to log a new GPS position at regular intervals of time regardless of the distance traveled since the last position logged. After tapping this option, tap the desired time interval.
If you wish to change the logging interval while you are logging a line feature, you first need to pause the logging of the feature: - Tap Options and then Pause - Tap Options again and then Logging Interval. Set the new logging interval as explained above. - After changing the logging interval, tap Options and then Resume . The receiver will continue to log the feature, but this time according to the new logging interval. 4.
The receiver determines the perimeter of an area feature by estimating the distance between successive points on the line feature with the assumption that each point is on a sphere of average Earth radius. The elevations of the points are not factored into the equation. Thus the receiver calculates the spherical distance rather than the horizontal or slope distance between the successive positions. The perimeter of the area feature is the sum of all these distances.
Selecting the Repeat Attributes option 6. Logging New Features with Same Attributes as Those Set in the Previously Logged Feature If you close a point, line or area feature and want to log the location of another feature of the same type and with an identical description, use the Repeat Attributes function. After closing a feature, ProMark3 takes you back to the Feature List screen on which the same feature type is still selected. Just do the following: - Move to the next similar feature you want to log.
Assuming you are logging a line feature and the Logging screen is displayed, do the following, for example to nest a point feature: - Tap Options and then Pause . This pauses the logging of the line feature. - Tap Options again and then Nest Feature - Move to the location of the feature you want to nest - In the Feature List screen now displayed, tap the feature type you want to nest. - Tap Log to start logging this feature.
Point Offset screen If you do not have a compass, you can use ProMark3’s Compass screen (see also page 145) to determine the bearing to the offset feature. If you have been moving for 5 to 10 seconds along a straight line, the Compass screen will tell you your bearing. You can use this to determine the bearing to the offset feature. CAUTION! The receiver cannot determine direction while stationary and the compass direction remains the same even if you rotate the receiver. Visual estimation for horz.
Line or Area Offset screen Line Area On the left On the right Visual estimation for horz. & vert. distances is usually good enough in terms of accuracy. 9. Offsetting a Line or Area Feature For the same reasons as a point feature (see previous page), you may need to use the offset utility to map a line or area feature. By combining the receiver’s position with the direction and the distance to the feature, ProMark3 will automatically calculate and record the location of the feature.
Press the down arrow to move the cursor to the next field. - Tap OK to return to the Logging screen. This writes the offset into memory, but you can edit it later if you like by going through the same process. Note: Offsets to area features are applied in MobileMapper Office and not in the receiver. To operate the grid mapping utility, you will need a measurement device - anything from a depth sounder to a ruler, your own sense of smell or your ability to make visual observations.
GOTO will not be shown in the menu list if you press MENU while the unit displays the Map screen in cursor mode. In that case, just press NAV and then MENU again. Grid Setup screen To log GIS data on a preset grid, do the following: - If you have created a waypoint to help you locate the first grid point, you can use any of ProMark3's navigation screens to get there. Press MENU and tap GOTO. Using the Left or Right arrow, make sure Alphabetical is selected at the bottom of the screen.
Spacing Column North Row (Heading= 0°) North Heading=21° Column Spacing Row In the two examples above: Columns=8 Rows=6 136 When you change the definition of a grid, ProMark3 always assumes that you are standing in the corner of the grid from which you can see the grid extend in front of you and to the right.
It is also possible to navigate to any grid point (or any location for that matter) on the Map screen by tapping over another grid point. After you record data at this location, you will still be prompted to go to the next grid point . - Navigate to the next grid point: When you have finished recording the first point feature, tap Done. A message prompts you to go to the next grid point. Tap Yes to navigate to the next grid waypoint and record the next point feature within the grid.
If you cannot physically occupy this point, but can make the necessary visual observation, you should do so and record an offset estimating the distance and bearing to the grid point. If you are recording measurements made by an instrument, you should NOT record an offset but rather try to make a recording as close as possible to the position.
Revisiting and Updating Existing GPS/GIS Jobs You can use ProMark3 not only to position and describe new GIS features but also to update information gathered previously. This is particularly useful when collecting data on things that change over time: streetlight bulbs burn out, new roads are added to housing developments, new crops are planted, etc.
Map screen showing straight line to target 140 - Tap Goto to ask ProMark3 to guide you to this feature. By doing this, you will make the selected feature your destination and all the navigation screens will be set to help you reach that feature. The Map screen will also be automatically displayed showing a straight line connecting your current destination to the selected feature. - Walk to the feature according to the navigation instructions provided on the Map screen.
2. Repositioning a Point Feature If a point feature appears to be mislocated on the Map screen, do the following after you have arrived at the feature: - Press the LOG key and tap the on-screen Log button. Let the ProMark3 recompute the point position and then tap the Done button to close the feature. Note that only point features can be repositioned. If you wish to reposition a line or area feature, you should record a new feature and then delete the old one in MobileMapper Office. 3.
Using ProMark3 as a Reference Station - Mount ProMark3 on a tripod placed over a control point, turn it on and then double-tap the Mobile Mapping icon. - Press the MENU key, tap successively Setup and Storage to choose the media (SD Card or Internal Memory; SD Card recommended) where to store the reference station data ProMark3 is going to collect. - Press the LOG key and then tap Reference Station. The Site ID screen is now displayed.
8. Navigation ProMark3 offers very helpful navigation functions that you can use while performing your field operations, whether Surveying or Mobile Mapping. The present chapter tells you how to use the navigation screens, how to create waypoints and how to work with the GOTO and Routes functions. Navigation Screens You will be able to view the different navigation screens only after launching the Surveying or MobileMapping application. The Map screen has two modes: Position and Cursor.
Select either On or Off for each screen until you see the Setup menu once more. Note that you must cycle through all the screens in order to put your selections into effect. The following is a description of each of the navigation screens. Map Screen Map screen in Position mode Map screen in Cursor mode The Map screen shows a map of the area surrounding your current location. Use the IN and OUT buttons to adjust the scale. The Map screen is always in the Position mode when you access this screen.
Compass Screen Compass screen The two data fields on top are customizable. The lower portion of the Compass screen displays your heading in a graphical manner. The Compass screen contains the following information, from top to bottom: - In the title bar: destination name if you are using the Goto function - Data Fields: customizable data fields (see Customize option on page 244). Some of the data displayed requires you to be moving to be computed. Invalid data is indicated by dashes.
Large Data Screen The Large Data screen is similar to the Compass screen but here the compass has been removed to allow for large display of the navigation data. This screen is ideal for when you have your unit mounted on the dashboard of a vehicle. Even from a distance the customizable information can be read with ease.
Position Screens Position screens 1 & 2 To switch from a screen to the other, just press the Left or Right arrow key. The same data as on Position screen 1 is displayed on Position screen 2 except that the lower part of the screen, containing the two data fields and the trip odometer field, is replaced with the current position’s coordinates expressed in the chosen secondary coordinate system and map datum.
Message Description Searching - 1st sat Searching for 1st satellite. Searching - 2nd sat 1st satellite found; searching for 2nd satellite. Searching - 3rd sat 2 satellites are being tracked; searching for a 3rd. Searching - 4th sat 3 satellites are being tracked; searching for a 4th. Collecting Data All satellites needed for position fix are being tracked and position is being computed. Averaging ProMark3 is computing fixes; speed is near 0.0 and so position is being averaged.
Road Screen Road screen The Road screen presents your route as if you were travelling on a road. When you need to make a turn, the road will graphically display the turn and the direction. Waypoint and destination icons will be displayed relative to your position as they come into view. Above the road is a compass that displays your heading and above that are four customizable data fields.
Data Screen When you need to see a lot of information in one place then you will appreciate the Data screen. The Data screen provides you with six data fields and an active compass that is the same as the one used on the road screen. You have the option of customizing this screen by selecting what data is displayed in the upper six fields. The lower portion of the screen is occupied by a compass providing your heading.
Speedometer Screen Speedometer screen The Speedometer screen displays your speed in a familiar graphical format. There are four additional data fields at the top of the display that can be customized to display the data that you need. The bottom of the screen contains a trip odometer that will record the distance travelled since the last time the odometer was reset.
Satellite Status Screen Although the Satellite Status screen is part of the navigation screen sequence, it is not actually a navigation screen. When ProMark3 is computing your position, an additional information appears in the right-upper corner with two possible values: 3D or 2D. 3D means the computed position is 3-dimensional (elevation computed). In 2D (2-dimensional), elevation is not computed. ProMark3 assumes that the last computed or entered elevation is the elevation for all computed positions.
GOTO Function Purpose You use the GOTO function to ask ProMark3 to guide you from your current position to a destination point. You will be able to use this function only after launching the Surveying or MobileMapping application. After you will have specified which destination point to go to, you will select your favorite navigation screen. You will then be able to read the information computed by ProMark3 to help you reach the destination.
Selecting a POI as the Destination Point GOTO will not be shown in the menu list if you press MENU while the unit displays the Map screen in cursor mode. In that case, just press NAV and then MENU again. 154 Press MENU and tap GOTO. The possible categories of POIs are now listed on the screen. Use the Up/Down arrow keys to highlight the category the destination point belongs to.
When these 20 points are listed, ProMark3 indicates the bearing and distance to your current position from the first point in the list. You can change the point from which the nearest points are found. With the Nearest To field now highlighted, press ENTER and scroll to the category where this new point can be found. Select a new point and press ENTER.
Saving Your Current Position as a Waypoint Mark screen Saving your current position as a waypoint is very easy and can be done from within the Survey or GIS function. From any screen, just press the MENU button, and select the Mark option. The Mark screen appears. This screen provides the description of the waypoint you are about to save.

Allows you to list the content of the parent folder.
11.Step-by-Step Procedure for Establishing a GPRS Connection Via Bluetooth Introduction You will use a cell phone associated with ProMark3 RTK to operate in NTRIP or Direct IP mode via a GPRS connection. The cell phone should be a Bluetooth-enabled device fitted with a “full IP” SIM card1 that allows a GPRS connection to be established with the provider. When first implementing a GPRS connection, you will have to go through a relatively long procedure.
Connection Profile Unknown The GPRS connection profile you want to use is not stored in your cell phone, or your cell phone does not let you list the profiles stored in its memory or SIM card. In this case, you will have to enter the parameters of the connection profile in the Dial-Up Connection window.
The First Time You Use ProMark3 RTK Please carefully read the procedure outlined in the table below. This procedure is described in detail in the continuation of this chapter. Please strictly follow the order in which the instructions are given. Note that the procedure was tested for several popular mobile phone brands and for a European GPRS operator. The procedure should normally apply for any other manufacturer, phone model and GPRS operator although this cannot be guaranteed.
Step 1: Ask ProMark3 RTK to Be Paired with the Cell Phone Start Bluetooth Manager 1. On ProMark3 RTK, double-tap the Settings icon and then the Bluetooth Manager icon. The Bluetooth window appears on the screen after a few seconds. For a quick overview of the Bluetooth Manager toolbar, please refer to Bluetooth Manager Toolbar Memo on page 197.
Ask for a Paired Bluetooth Link This procedure is for securing and quickly re-establishing the Bluetooth connection between the two units. 1. Tap and hold the cell phone icon. 2.

13.Accuracy RTK Operating Conditions Unless otherwise mentioned, all performance figures given in what follows were collected in kinematic mode and open sky environment. Open sky is defined as: - No obstructions above 10-degree elevation - No metal-like reflectors within 100-meter radius - More than 5 satellites tracked above 5-degree elevation - Maximum SNR value is greater than 52 dB.Hz. - No satellite above 10-degree elevation has an SNR figure less than 30 dB.Hz (external antenna used).
Time to First Fix (TTFF) Conditions of use: External antenna used, baseline < 10 km, difference of altitude between base and rover <50 m Parameters Fix Availability within the next 600 sec Reliability TTFF for 50% of the tests Sky Environment OTF Static (Static OTF) With Initializer Bar Open Sky >80% >90% >99% Partly blocked sky >60% >70% - Open Sky >99% >99% >99% Partly blocked sky >99% >99% - Open Sky <120 s <90 s <30 s Partly blocked sky <150 s <120 s - Initialization in Net
Autonomous GPS, SBAS & DGPS Modes To achieve the best accuracy, it is important to hold the receiver at an angle of 45 degrees from horizontal. This allows the internal antenna to pick up signals from the GPS, WAAS and EGNOS satellites. This is especially true when recording data for post-processing. 224 ProMark3 provides autonomous 3-meter accuracy all around the globe assuming the receiver is tracking five GPS satellites and the PDOP < 4 (which is almost all the time).
ProMark3 may warn you if the PDOP, and therefore the accuracy, of your positions has dropped below the level you selected during Setup (see page 240, the PDOP alarm option). If you see this warning you may press the ESC button and continue logging. However, if you are running a kinematic survey or recording line or area features, you might want to return to the field when the GPS satellites are in a better configuration overhead (the constellation changes slowly but constantly).
14.MENU key The MENU key is inactive until you double-tap the Survey or Mobile Mapping icon. The diagram below shows the available functions when pressing MENU. When you select the Setup option in the menu list, another menu is displayed containing a number of options, as shown in the diagram below.
DGPS Configuration This option is available only with a ProMark3 RTK after you have set the Receiver Mode to Real-Time or Real-Time & Raw Data Recording. This option provides access to the DGPS Configuration Utility from within Surveying or Mobile Mapping. See this utility in Selecting a DGPS Mode on page 209. The DGPS Configuration Utility can also be run from the ProMark3 workspace, or from the Utilities folder, by doubletapping the corresponding icon.
Base Station This option allows you to set the ProMark3 RTK as a base station. Setting a base station includes defining: - The three coordinates of the point occupied by the base station (Location, Elevation), - The height of its antenna with respect to the reference point (Antenna Height), how the antenna height was measured (Height Type), and the unit in which the height is expressed (Units), - The station ID (Station ID).
The name, last modification date and size of the selected file is shown at the bottom of the screen. Only the following file types are listed: - *.O* (vector files; ProMark3 RTK only) - R*.* (Raw data files) - *.MMJ (GIS job files) - *.MMF (GIS feature library files) - *.IMI (Map files) You can delete the selected file or all the files by tapping respectively Delete or Delete All and then Yes to confirm.
On the other hand, if you have to change any of these parameters or add a comment in the Message field, then you have first to edit the corresponding fields before selecting the Save field and pressing ENTER The Route button gives direct access to the Route List screen where you can insert the newly created waypoint into a new or existing route.
Routes This option is discussed in detail on page 158. The MENU button gives access to a list of specific options when the Routes option is enabled. This is summarized in the diagram below.
Setup Menu Storage This option allows you to choose the media to which ProMark3 will save the data collected in the field. There are two possible choices: • Internal Memory • SD Card In surveying, your choice of storage media is reminded at the bottom of the logging screen: • “SD Card” is displayed inside the lower-right rectangle if you chose the SD Card • Nothing is mentioned in that rectangle if you chose the internal memory.
Real-time Fast Mode This option allows you to define the way the received RTK corrections are processed in the ProMark3 RTK. Set this option to match your application. Some applications require the fastest possible position output rate whereas some others can do with a slower ouput rate provided the position accuracy is maximum. Two settings are possible for this option: • ON: Enables the real-time Fast mode.
Select Map This option is mainly used to choose the background maps (vector map and/or raster map) that ProMark3 will display on the Map screen. The following parameters can be set on the Change Map screen: - Basemap: Only the Default Map option can be selected in this field. The default map – an American or European map – is always present in ProMark3. - Detail Map: Select the desired vector map from the list attached to this field.
Map Setup Map Setup screen, Format tab Auto Auto Detailed Fixed Rate This option allows you to set the viewing options for the Map screen. On the Format tab, you can set the following parameters: - Orientation: You can change how the map is orientated on the screen to either North Up, Course Up or Track Up. Default is North Up. - Detail: Use this field to set the detail for both the basemap and the detail map. This field can be set to highest, high, medium, low or lowest.
Map Setup screen, Display tab 236 Please note that the Track Mode will be automatically set to Off when you start logging a new feature in the open GIS job (using the Mobile Mapping application). This is to avoid confusion on the Map screen between features and track points. The Track Mode will be automatically restored with its initial settings when you close the GIS job. - Primary Usage: ProMark3 can be set to either Land or Marine usage.

Installing New OS Languages (Chinese, French) To install the Chinese or French version of the operating system into your ProMark3, you need an office computer with a card reader that is compatible with the SD card used in the ProMark3. Assuming the currently running ProMark3 operating system is in English, follow the instructions below: 1. Insert the SD card from your ProMark3 into the SD card reader on your office computer. 2. Copy the “language.
Installing the ProMark3 RTK Firmware For all ProMark3 units purchased before June 2007, and for all those units purchased after this date without the RTK function, you first need to download the ProMark3 RTK firmware from the Magellan FTP server. The firmware is available as a zip file. Follow the instructions below: - Download the zip file to your office computer. - Extract the files from the zip file, making sure you preserve the folder structure while doing this.
Installing Optional Functions in FAST Survey To purchase an optional FAST Survey function (Total Station or GPS), first run FAST Survey, go to Equip> About Fast Survey>Change Registration and read the registration code on the Product Registration screen. Provide your registration code when ordering an optional function. You will receive in return a Serial Number and a Change Key specific to your FAST Survey license. Enter these two codes on the same Product Registration screen to activate the function.
Assessing MobileMapper Beacon Reception Quality As long as the green lock indicator light on MobileMapper Beacon stays on, you can be certain that ProMark3 can readily deliver a DGPS solution using the incoming correction data packets from MobileMapper Beacon. But if you notice that the green indicator light on MobileMapper Beacon sometimes temporarily turns off, this means the signal received is not as strong as it should be.
Glossary Attribute: A description item of a feature. Attribute value: One of the possible values that can be ascribed to a feature. Base: A reference station operated in static mode. B-File: A binary data file containing GPS measurement data. Baseline: A three-dimensional vector connecting the base to the rover. The baseline length is the vector modulus. Carrier phase data: Phase angle measurements for the 1575 MHz radio wave carrying the GPS coded messages.
To log a feature: Means to save the characteristics of a feature into the receiver memory. The user is in charge of entering the description of this feature whereas the receiver is responsible for saving the GPS position(s) it has determined on this feature. To describe a feature: Means to give each attribute of the feature one of the prompted values for this feature. Feature Library: A file containing all the feature types required for a given job. (In fact we should say “Feature Type Library”.
Job file: File containing a feature type library and a collection of features that grows as you log new features in the field with this job file open. All the features in the job file necessarily “originate” from the feature types present in the job file’s feature type library. Nesting: This word is used to describe a feature that you are logging whereas another feature is already being logged. NTRIP: Networked Transport of RTCM via Internet Protocol.
