1. Introduction What is the ProMark3 System? ProMark3 is a complete GPS system providing precision surveying, GIS feature collection and navigation. A typical ProMark3 system includes two ProMark3 GPS receivers, GPS antennas, and all ancillary components required to get you up and running and producing quality data in a minimum amount of time. x2 Surveying The ProMark3 system utilizes standard tripods or fixed-height GPS tripods to position system components above a given survey point.
The ProMark3 System operates in conjunction with GNSS Solutions, Magellan Navigation’s highly-automated GPS postprocessing engine. GNSS Solutions is a complete, easy-to-use software package which manages and processes raw GPS data, deriving precise positioning data and presenting the results in easily understood report formats. Mobile Mapping The ProMark3 receiver enables you to map and describe GIS features and then format the data so that later it can be uploaded to a GIS.
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 & MobileMapper Office Software CD This CD includes the MobileMapper Office software required to interface ProMark3 with your GIS and post-process your field data. This CD also includes the ProMark3 Getting Started Guide and the ProMark3 Reference Manual. 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.
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 below).
Specifications Parameter 10 Specification GPS survey mode supported Static, Stop-and-go, Kinematic Survey accuracy (RMS) Static Horizontal: 0.005m + 1 ppm Vertical: 0.010m + 2 ppm Survey accuracy (RMS) – Stop-and-go Horizontal: 0.012m + 2.5 ppm Vertical: 0.015m + 2.
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.
When you start a new GIS job, ProMark3 asks you to: 1. Choose a feature library for the job. A feature library lists all the possible feature types you will see in the field. It also provides all the possible attributes for each feature type and all the possible values for each attribute. After you have chosen a feature library, you will only be able to log features that comply with those prompted in this library.
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 recon 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 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.
Stop-and-Go Since the Stop-and-Go method requires an initialization, the occupation times are much shorter than the static method. Initialization on a known point can be accomplished in as little as 15 seconds with a 1 second recording interval. Initialization with the initializer bar is typically 5 minutes. Stop-and-Go point occupations can be accomplished in as little as 15 seconds with a 1 second recording interval.
For jobs performed in post-processing mode, the time requirements are those defined above for Stop-and-Go and Kinematic surveys keeping in mind that all GIS/Mapping jobs implicitly use an OTF initialization. Where to Find Information This manual is designed to guide you through the ProMark3 Surveying and Mobile Mapping procedures as well as provide general reference.
2. Preparing For First-Time Use Charging the ProMark3 Battery Pack Battery Life 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. Control Buttons Scrolling button Power button (red) Alphanumeric keypad Under the screen you will see eight buttons located around a large oval “scrolling” button with 4 directional arrows on it. IN/OUT: Use these buttons to zoom in and out when viewing a screen with a map displayed. ESC: Takes you back to the previous screen without effecting any changes or scrolls navigation screens in reverse order.
NAV: Takes you to the various navigation screens where you can locate yourself and navigate to waypoints and features. LOG: With no job started yet, gives access to the Survey screen or lets you create or open a GIS job. With an already started job and with a navigation screen displayed, takes you back to the Survey or GIS screen last displayed. ENTER: Use this button to accept highlighted input and to initiate various functions. MENU: Valid only after you have entered the Survey or GIS function.
Alphanumeric keypad: ProMark3 uses a telephone-style alphanumeric keypad. Buttons 2-9 contain alphanumeric characters. By pressing the key repeatedly, all characters on that key will be scrolled. For example, the letters a, b, and c are associated with the “2” key. Tapping the key once enters an “a,” twice enters a “b,” three times enters a “c” and four times enters a “2.” Note that the “0” key includes the backspace.
Turning On/Off the Receiver ProMark3 start-up screen Once you have charged the battery, hold down the red key (the power button) 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 4 main icons: Surveying, Mobile Mapping, Settings and Utilities (see opposite right).
Automatic System Time Update ProMark3 will automatically update the system date & time using the GPS time determined by the integrated GPS receiver and the time zone that you specify. To set the time zone: • In the ProMark3 workspace, double-tap the Settings icon. • Double-tap the Date/Time function. This opens the Date/ Time Properties screen. • Set the time zone field (see opposite) and then select OK on top of the screen.
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, double-tap successively the Utilities icon and then the GPS Init icon.
DGPS Real-Time Configuration The ProMark3 GPS receiver integrates SBAS signal reception. You can also use corrections from an external correction source, such as MobileMapper Beacon, a belt-mounted, Bluetooth-enabled beacon receiver connected to serial port COM1 or via a Bluetooth port, or from any other RTCM source. For more information on using ProMark3 with an external corrections receiver, refer to Using MobileMapper Beacon on page 184 or Using Another RTCM Source on page 190.
Preliminary Settings Now that ProMark3 displays a navigation screen, press MENU and double-tap Setup. There are many options to select among, and all are explained in full in Setup Menu on page 149. For the purposes of getting started, however, we will concentrate on just a few of these options. As a general rule, tap an option to open the corresponding setting window. Then tap the desired value. This will enable the value and take you back to the Setup menu.
Units You select this option to set the units of measurement you want to use. Units are presented in this order: long distances, short distances, speed and area. You can set these units to “kilometers, meters, kph and hectares” or “miles, feet, mph, acres” if you like, or to three other standard sets of units.
3. 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. 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. 48 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 192.
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. Initialization achieved in 15 seconds Base Rover Init point can be several kilometers away from the base.
“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 56 The base is setup and operated in the same way as it is in static surveys (see page 45).
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 58 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. Skip step 3 when next using the Surveying function.
Slant 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. 60 • 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. 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. So be sure from now on, and until the end of the survey, that you will not mask the antenna.
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 192. • Current Power and Memory statuses in graphical form. 11.Wait until Remain = 00:00:00.
0001 0002 Rover 0003 0004 0007 0006 0005 Cross points indicate where static occupations take place. The line indicates continuous data collection, from the first to the last point. 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 68 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. Skip step 3 when next using the Surveying function.
Slant 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. 74 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.
Office Work with GNSS Solutions Software Do not forget to double-tap the Surveying icon or else no communication will be possible between ProMark3 and the PC. Downloading Field Data from ProMark3 Back in your office, do the following to download your field data. It is assumed that GNSS Solutions has already been installed on your PC. 1. On ProMark3: - Turn on the receiver. - Double-tap the Surveying icon.
It is very important that you connect the ProMark3 to the PC BEFORE running Download. If you have some difficulty identifying which port number should be selected as the USB port, first run Download WITHOUT the USB connection to ProMark3 in order to list the available ports. Then quit Download and resume the operation after connecting ProMark3. An additional port will then appear in the list. This additional port is precisely the port you need to select to allow communication with ProMark3 via USB. 80 4.
Files resulting from the downloading of an observation file are named as follows: X where prefix X = “E” for Ephemeris Data, “B” for Position Data, “D” for GPS Raw Data and “W” for SBAS Data. After the transfer is complete, notice in the right side of the Download window that each downloaded file has been split into different files named with different prefixes (see opposite). - Close the Download window. 5.
Downloading Field Data from the Local SD Card Reader If your field data were logged on the SD Card, you can also download the field data from your local SD card reader if there is one. - Extract the SD card from the ProMark3 and insert it into your local SC card reader. - From the Windows task bar, select Start>Programs>GNSS Solutions>Tools>Download. - (Double-click in the right side of the window if you want to change to the parent directory and open your project folder on the PC.
Post-Processing Field Data 1. On your office computer, launch GNSS Solutions 2. Click Create a New Project, enter a project name and then click OK. 3. Click Import Raw Data from Files. 4. Browse your computer to change to the folder containing the data files you have just downloaded. 5. Select the files you want to import and click Open. The Importing GPS Data dialog lists the files you want to import (top). Each row describes one of these files (filename, associated Site ID, etc.) 6.
The longest observation is likely to be the one recorded at the base. Refer to the GNSS Solutions Reference Manual for more information. 7. Click OK>To Import to import the data into the project. Depending on the type of survey, you can go even faster by running, in one operation, the Import, Process and Adjust functions. Uploading a Vector Background Map to ProMark3 Vector background maps are generated from DXF, SHP or MIF files imported in a GNSS Solutions project.
Here is a screen example that you could see at this stage: - Name the file and then click OK. The following messages appear in succession during the map upload process: Preparing data.. Creating data Creating output image file... Connecting... USBx Uploading to GPS - While the last message above is displayed, a message on the ProMark3 screen informs you that the
Uploading Control Points to ProMark3 Control points can only be uploaded to the ProMark3’s internal memory! Ctrl 86 Wpt You can uploads control points from an open GNSS Solutions project to your ProMark3. Reference and target points CANNOT be uploaded. To know the definition of each of these point types, please read the “Point Properties” section in the GNSS Solutions Reference Manual (in Chapter 5).
Uploading control points, whether fixed or not, will always overwrite the complete list of control points currently available in the ProMark3. This means for example that there won’t be any control points left in the ProMark3 if the selection of points you wish to upload does not include a single fixed control point. As a general rule, you should therefore upload all the control points and waypoints you need through a single upload operation.
- In the Command pane on the left, click the Export topic bar and then the Upload Positions to External Device icon. In the new dialog that opens, select Control & Waypoints: - Click OK. GNSS Solutions then automatically detects the presence of the ProMark3 on the USB port.
- Click OK. The following messages appear in succession during the point upload process: Connecting... USBx Uploading control points and waypoints... - The points you have uploaded can now be seen on the ProMark3 using the following procedure: • Press MENU and tap Exit • Double-tap Surveying • Press LOG • Select Stop-and-go or Kinematic as the Survey Mode • In the Initialize field, select Known. The list of available control points now appears in which you can recognize the points you have uploaded.
4. 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 Implementing Real-Time DGPS on page 182.) 1. Turn on the receiver by pressing the red button. 2. Double-tap the Mobile Mapping icon. 3.
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 107).
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 125). 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 128) 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=6 104 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 108 - 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.

Viewing/Analyzing the Content of a Job Run MobileMapper Office and then use the File>Open command to open one of the MMJ files you have previously downloaded. As a result, MobileMapper Office shows the content of this job in the main window. Here is an example of a job open in MobileMapper Office: First of all, you can see the list of layers present in this job in the lower-right corner of the screen.
The main purpose of viewing a job in MobileMapper Office is to get a view of the features that were logged during field operations. If enabled for display, these features are represented on the Map Display area according to the viewing choices made for the corresponding layers. You can do more than just view these features. You can also view the conditions in which these features were logged. To do that, just click on these features, one after the other in the Map Display area.
The Feature Properties window provides the following information: • Feature name and geometry, number of points for lines and areas only, measurement(s), user-settable Updated field. Apart from the Updated field, these are non-editable properties.
The correction type may be one of the following: - “WAAS” - “RTCM” - “Post-processed” - “Uncorrected” (for autonomous positions) “Real” feature d Direction of travel along the feature Feature offset to the left by distance d • Accuracy Estimation for the selected point: horizontal error, vertical error (non-editable). • Offset data (editable): direction (for line or area) or bearing (for point), horizontal distance, vertical distance.
Uploading a Vector Background Map Vector background maps are generated from DXF, SHP or MIF files imported in MobileMapper Office’s Map Editor. Note that raster background maps CANNOT be uploaded to ProMark3 in its current version. It is all or part of the background map attached to MobileMapper Office’s Map Display area that can be uploaded. The background map is output as an IMI file.
The limits of the region are now represented with a rectangle. You can still resize or reshape the rectangle by dragging its control points (corner and mid-side points). You can also move the whole rectangle by dragging the mouse cursor from inside the rectangle. - When the location and size of the region is okay, click outside of this region.The region is now defined and its limits are represented by a thick green line. NOTE: To delete the region and start over, resume the above three steps.
• If the map filename uses more than 8 characters, MobileMapper Office will warn you that this name will be truncated. Keep the truncated name or type a different name and then click OK. • Wait until the uploading messages on the PC and ProMark3 disappear. • When the upload procedure is complete, press MENU on the ProMark3, tap Setup and then Select Map. • Tap in the Detail Map field and then select the name of the file you have just uploaded • Tap Save. ProMark3 starts loading the new map.
Uploading Jobs and Waypoints to ProMark3 To create a waypoint in a job: Click on in the MobileMapper Office toolbar and then click where to create the waypoint on the Map Display area. If necessary, adjust its coordinates, icon and name in the edit box on the right. For more detail, please refer to the Using the Waypoint/Route Editor Chapter in the MobileMapper Office User Manual. Jobs and waypoints associated with jobs are uploaded through the same procedure.
Uploading Jobs and Waypoints to the Local SD Card Reader If you are using the SD card in the field rather than the ProMark3’s internal memory, you can also copy your MMJ and MMW files to the SD card using the MobileMapper Transfer utility and your local SD card reader. - Extract the SD card from the ProMark3 and insert it into your local SC card reader. - From the Windows task bar, select Start>Programs>MobileMapper Office>MobileMapper Transfer.
Exporting to GIS - Open the job containing the data you want to export to your GIS. - Run the File>Export function, select the format in which to export the data, name the export file and click Export. For more information please refer to the MobileMapper Office User Manual (also provided on the ProMark3 CD).
5. Accuracy 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. 124 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 157, 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).
6. 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 128 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 162). 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.
Road Screen Road screen 132 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 134 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. 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. You can accept all the defaults by simply pressing ENTER (Save field already highlighted).
Select Item screen - Tap the waypoint you want to edit/delete. This opens the User Waypoint screen on which you can see the definition of the waypoint (coordinates+comments). At the bottom of the screen are three command fields that you can use for the following tasks: Edit (default choice): Select this field if you want to edit the definition of the waypoint. The following parameters can be changed: icon, name, coordinates, elevation and comment.
Routes You will be able to use this function only after launching the Surveying or MobileMapping application. As explained below, ProMark3 can handle two types of routes: GOTO route and multi-leg route. GOTO Route A GOTO route is a one-leg route whose two ends are your current position and the chosen destination point.
Create Route screen Route List screen 142 1. Creating a Multi-leg Route - Press MENU and tap Routes. The Route List screen is now displayed. - Tap the first Empty route in the list. - Press MENU and tap Create New Rte. The Create Route screen is now displayed and the first line on this screen is highlighted. - Press MENU and tap Insert WPT. The Insert WPT screen is now displayed. - Press the Left or Right arrow to select Alphabetical at the bottom of the screen.
3. Asking ProMark3 to Retrace your Steps If the Track Mode is active (see page 151), the ProMark3 automatically creates and stores hidden points into memory as you move. This series of points is called the “track” or “track history”. To retrace your steps, do the following: - Press MENU and tap Routes. - Select Backtrack. - Press MENU again and tap Activate Backtrk. A message appears warning you that the Track History Logging is now disabled. - Tap OK and press NAV to return to the Map screen.
5. Other Functions Tied to Routes You can also do the following on the highlighted route using the functions available from the MENU button (see also diagram on page 148): - Viewing the route on the Map screen by pressing MENU and tapping Map View Route. The Map screen then appears showing the route. Press ESC to come back to the Route List screen. - Editing the route by pressing MENU and tapping View/Edit Route.
7. 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. (Not available if Map screen displayed in cursor mode) (Available only when a customizable navigation screen is displayed) File Manager Mark GOTO Routes Setup Customize About...
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: - R*.* - *.MMJ - *.MMF - *.IMI You can delete the selected file or all the files by tapping respectively Delete or Delete All and then Yes to confirm.
When you select Mark in the menu list, ProMark3 displays the Mark screen with the following default values: - Default icon in the Icon field - “WPTxxx” as waypoint name in the Name field.
Routes This option is discussed in detail on page 141. 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.
Select Map This option is mainly used to choose the background map (Detail 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 – a worldwide map – is always present in ProMark3. - Detail Map: Select the desired background 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 152 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.
Check the items you want to show and clear those you want to hide. You can also check or clear all these items in a single operation by respectively selecting Mark All or Clear All just above these items. Press ESC or NAV to quit the Map Setup screen. Nav Screens This option allows you to remove the navigation screens that you do not need from the navigation screen sequence that you scroll by pressing NAV repeatedly (see page 126).
Coord System This option allows you to define a primary coordinate system, and also a secondary coordinate system if you need one. By defining a coordinate system, you tell ProMark3 how the calculated coordinates should be expressed. For example, if you choose Lat/Lon, all coordinates will be expressed as angles (latitudes and longitudes) and if you choose UTM or any other system, coordinates will all be distances (Northings and Eastings) from the chosen origin.
- For some systems, you are asked to supply information on grid zones or types - For the User Grid, you are asked to supply a projection type (Transverse Mercator, Lambert Conic, Stereographic, Oblique Mercator or Polyconic), coordinates of origin, scale factor, unit to meters conversion and false Easting and Northing at origin Notes on Coordinate Systems: - The ProMark3 always uses the WGS 84 coordinates to locate the features and waypoints on the Map screen, even if you select some other coordinate system
Map Datum This option allows you to define a primary map datum, and also a secondary map datum if you need one. A map datum is a geographic reference that ProMark3 will refer to to calculate the coordinates of your position. ProMark3 holds more than 70 different map datums in its memory. After selecting the Map Datum option from the Setup menu, tap the map datum that applies to your country and working area.
Units This option allows you to select the units of measurement that will be used when displaying navigational data or features being logged. All sets of units are formatted as follows: long distance unit/ short distance unit/speed unit/area unit. You can select from 5 different sets of units. You can also create your own set of units by selecting Advanced at the end of the list. You are then prompted to specify the unit you wish to use for each type of possible measure, i.e.
This option allows you to set how close you must come to the destination before the alarm begins to sound. After the alarm sounds, you can reset the arrival alarm to a shorter distance, but this shorter distance will apply to the next target and not to the current one. If you want the alarm to sound again when you come within a shorter distance to the current target, first select another target destination and then reselect the original target.
North Reference This option allows you to define the type of North reference you want ProMark3 to use. This can be True North, Magnetic North, Military True North or Military Magnetic North. After selecting the North Reference option from the Setup menu, tap the desired North Reference from the displayed list. Beeper This option allows you to enable (On) or disable (Off) the beeper. After selecting the Beeper option from the Setup menu, tap the desired option.
Clear Memory This option allows you to clear one of the following data sets from ProMark3’s memory: - Track history: Will clear the track shown on the Map screen. - Wpts/Routes: Will clear all waypoints and routes from memory. - Routes: Will clear all routes from memory. - Reset default: Will reset the receiver by restoring all factory defaults. - All: Will clear all memory.
Simulate This option allows you to set the simulator. It shows you how ProMark3 uses its various functions based on a simulated journey. The simulator is useful for learning or demonstrating ProMark3’s GPS functions when indoors and there is no GPS reception. When the simulator is on, ProMark3 quits normal operation to operate in the simulator mode. You can choose one of the following three options when you access the Simulate option: - Off: Will turn the simulator off.
Customize The Map screen must be in Position mode if you wish to customize data fields. If the Map screen is in cursor mode (cursor is a crosshair), press ESC to return to the Position mode.

11.Implementing Real-Time DGPS The real-time DGPS functionality is needed in your ProMark3 when your applications require that the unit deliver submeter positions while you are working in the field. There are three different ways of providing ProMark3 with the differential correction data needed for real-time DGPS: • Using SBAS (Satellite-Based Augmentation System). SBAS encompasses WAAS in the North American continent and EGNOS in Europe.
Using SBAS This is the easiest way of implementing real-time DGPS in ProMark3. As the correction data broadcast by SBAS uses the same transmission channel as GPS, you don’t need any additional equiment or cable. Receiving correction data will only require one GPS reception channel in ProMark3. The allocation of this reception channel will be managed internally so you won’t have anything special to do except for the following: • On the ProMark3 workspace screen, double-tap Utilities and then DGPS Config.
Using MobileMapper Beacon Magellan’s MobileMapper Beacon can be used to provide ProMark3 with real-time DGPS correction data from any beacon networks operated worldwide. The connection between these two units can be achieved in two different ways: • Via Bluetooth • Or via a serial cable using the RS232 protocol. Via Bluetooth Using ProMark3’s DGPS Configuration and Bluetooth Manager utilities, tuning the beacon receiver and monitoring its performance through wireless communication is a simple process. 1.
• Tap the plus sign box next to the beacon device name: • Double-tap “Bluetooth Serial Port” to configure this port. • Freely choose one of the listed ports (“COM3” for example): • Tap OK. • Tap OK in the Bluetooth Manager window.
• Double-tap the Utilities icon and then the DGPS Config icon • Tap Beacon and then tap the Open Port button • In the list attached to the Port field, select the same port as the one you chose earlier in the Bluetooth Manager window. Keep the default settings for the other fields. • If you tap the Test button, a message will appear informing you that the port is now available for read/write operations. Tap OK to close this message.
2. Tuning the MobileMapper Beacon Receiver • Still in the DGPS Configuration window, select the Tune pane • Choose one of the following options to tune the MobileMapper Beacon receiver: - Tune Automatically: Automatic method (default choice). - Tune by Frequency: Manual method. You are supposed to know the reception frequency (range: 283.5 to 325.0 kHz in 0.5-kHz steps) and the MSK rate (100 or 200 bits per second) used by the reference station you wish to use. - Tune By Site: Manual method.
To read this information, you just need to select the Status pane in the DGPS Configuration window: • Finally, tap OK on top of the DGPS Configuration window for all the settings to take effect. A new message appears confirming the acquisition of RTCM data via the selected port. • Tap OK to close this message window. • Tap OK to close the DGPS configuration window. Your ProMark3 will now operate in real-time DGPS mode.
Via a Serial Link 1. Establishing Communication Between the Two Units - Clip the I/O module to the ProMark3 - Use the data cable provided with the MobileMapper Beacon to connect this unit to the ProMark3 RS232 Port (COM1). Port COM1 is located on the I/O module. - Turn on the two units (ProMark3 and Beacon). When you turn on the ProMark3, a message is displayed indicating that an RTCM source is used on COM1: (but in fact the port is not open yet for use).
Using Another RTCM Source You can use another equipment used as the RTCM source. In this case, see the manufacturer’s instructions to know how to connect this equipment to the ProMark3. On ProMark3 side, you just need to: - Run the DGPS Config utility - On the Mode tab, tap Other RTCM Source - Then tap Open Port, select the port used, make the necessary settings and tap OK. - Tap OK to close the DGPS Configuration window. A message will tell you that the RTCM source is now used in ProMark3.
12.Appendices Main Alarm Screens Alarm message Alarm Acknowledge: Tap anywhere on the screen outside of the alarm window to acknowledge (erase) the alarm message. The “Not enough satellites...” and “No external antenna...” messages will also automatically disappear when the condition that triggered the message also disappears. Description & Action Required (Surveying only) You are trying to start data collection with no external antenna connected to the unit.
File Naming Conventions Survey Data Collection Any file created while collecting survey datais named according to the following conventions: R2050A05.257 Day number when file was open Year (last 2 figures only) Session ID Receiver ID File Prefix The session ID increments A-Z, which provides up to 26 unique session IDs for any given day number. If more than 26 files are collected in one day, the first digit of the year is used as part of the session ID.
GIS Post-Processing Suppose you have created a new job named “JOB1.MMJ.” You selected the post-processing job mode in ProMark3 so that it records GPS measurement files in addition to JOB1.MMJ. The table below illustrates how these files will appear at various stages of the differential correction process: Rover file seen on receiver JOB1.MMJ Rover file seen on MobileMapper Transfer’s left window, before download JOB1.MMJ Rover file seen on MobileMapper Transfer’s right JOB1.
Defining a User Map Datum The receiver software allows you to define the full set of 9 parameters defining a map datum. After pressing MENU and selecting Setup>Map Datum>Primary/Secondary and “USER” in the prompted list, you now have access to two different screens on which these 9 parameters are presented: 1st screen: Delta A (meters) Delta F (X 10,000) Delta X (meters) Delta Y (meters) Delta Z (meters).
