English Initializing GPS GPS satellites are 12,000 miles overhead. The first time a new GPS receiver is turned on, it might have difficulty calculating its position. To help the receiver calculate its first position, you should “initialize” it. You have to do this when: - The receiver is brand new. - You have moved more than 500 miles from the last place you were using it. - GPS receiver has been reset. - Or the receiver has not been used for more than a few months.
The GPS Settings tool is used to set the environmental conditions in which the unit is to be used. These settings have an impact on both the availability and accuracy of the position computed by the unit. Select the tab, then Programs>GPS Utilities>GPS Settings to run the GPS Settings utility. The following parameters are displayed (see screen opposite): • Open Sky: Check this option if you are working in an open sky area. • Tree Canopy: Check this option if you are working in a forested area.
English - Minimum SNR: SNR stands for Signal-to-Noise Ratio. Ensure your SNR mask is not set too low (less than 20). GPS signals with lower SNRs will be very noisy and contribute to accuracy degradation. - Elevation Mask: Angle that specifies that any satellite must be at least a specified number of degrees above the horizon before the signals from the satellite are to be used.
This window allows you to monitor Signal/Noise ratios for received satellites. This information is shown in graphical form (see opposite). The signal quality window will grow or shrink to accommodate the number of satellites in view. The Position pane provides the coordinates of the current GPS position, including elevation or altitude, and the number of satellites (used and received). Azimuth and Elevation Graph (Azmth/Elvn) This graph shows all the satellites currently in view.

The set of GPS utilities provided in the Start menu allows you to configure and monitor MobileMapper CE’s internal GPS receiver. This chapter describes the full set of GPS Utilities, which includes the following items: - DGPS Configuration - GPS Initialization - GPS Ports Configuration - GPS Reset - GPS Settings - GPS Status - Mission Planning Note that some of these utilities have been described earlier in this guide (see Preparing for First-Time Use chapter).
English GPS Ports Configuration Using the GPS Ports Configuration utility, you can ask MobileMapper CE to output data messages to another device through the GPS auxiliary output port or to the application running on MobileMapper CE through the GPS VSP output port (VSP=Virtual Serial Port; this port is also known as COM2). Using this utility, you can therefore: • Enable or disable the GPS auxiliary output port. • Change the settings of the GPS auxiliary output port.
NOTE: To output GPS from MobileMapper CE to another computing device via serial port (RS232), you must connect the two devices using a null modem cable. GPS Reset Use the Reset GPS utility to cause the internal GPS receiver to re-initialize. You may need to run this utility if for example you want to force the GPS receiver to acquire new almanac data from the GPS constellation and then use this data in the position computation process. - Tap on , then Programs>GPS Utilities>GPS Reset.
English As explained in the GPS Reset window, you may reduce the time to first fix by running the GPS Initialization utility (see Initializing GPS on page 12). Until a new almanac file is received from the GPS constellation, MobileMapper CE uses a non-erasable almanac file stored in its memory to start the satellite acquisition process. GPS Settings See Setting Up GPS on page 13. GPS Status See Viewing Current GPS Status on page 14.
Function English Icon Screen Tap this icon to close the Mission Planning utility window. - Tap this icon to choose the location on Earth for which Mission Planning will determine the GPS constellation. - You can key in the exact coordinates of your site or directly tap on the map to indicate where this site is (see screen example opposite). Tapping on the map automatically updates the coordinates in the Latitude and Longitude fields. - Then tap OK to validate these coordinates.
English Switching Between Two Utilities Use the icon located at the far right in the task bar to switch from a running application to another. For example if DGPS Configuration and GPS Status are both running in the background while using Mission Planning, the menu opposite will pop up when you tap this button. Just tap the name of the application you want to go to.
This chapter gives general information on MobileMapper CE’s Bluetooth Manager module. For detailed information on how you can establish a GPRS connection via Bluetooth Manager, please refer to Step-by-Step Procedure for Establishing a GPRS Connection Via Bluetooth on page 17.
English Bluetooth Range The maximum range in class 2 devices is 10 meters (30 feet) typically. A minimum distance of about 60 cm (two feet) should be observed between any two Bluetooth-enabled devices. First Steps with Bluetooth Manager Starting Bluetooth Manager - Tap >Settings>Control Panel and double-tap Bluetooth Manager. The Bluetooth window appears on the screen after a few seconds. Note the presence of the icon in the task bar.
- Tap every time you need to refresh the list of Bluetooth-enabled devices present nearby. NOTE 1: is only active after has been tapped.

In this case, tap and hold the “Unknown” icon and then select Update in the pop-up menu to let Bluetooth Manager determine these parameters. PIN Code, Detectability & Authentication - Tap in the Bluetooth Manager toolbar.
English - To demand that a remote device be allowed to access the local services only after pairing itself with MobileMapper CE, check the Enabled box underneath Authentication. Otherwise keep this option disabled (check box cleared). Caution! This option is automatically disabled every time you start Bluetooth Manager. - Tap OK on top of the window for the changes to take effect.
• Tap in the Bluetooth Manager toolbar. • Tap and hold the icon representing the local service you want to deactivate and then select Stop. This instantly stops the concerned local service. Note that when you deactivate the File Transfer Service or Object Push Service, you automatically deactivate these two services. To re-activate a local service: • Tap in the Bluetooth Manager toolbar. • Just tap and hold the concerned icon and then select Start.
English • GPS output is enabled via the COM port assigned to the Serial Port Service (COM3 in our example) (see GPS Port Configuration, page 44). • Remember ALL the COM3 settings as you will need them on the computer (see GPS Port Configuration, page 44). - On • • • • • • • the computer: Run Bluetooth. Detect MobileMapper CE. If required, pair the two devices (you’ll need to enter the PIN code defined in the MobileMapper CE Bluetooth properties; see page 51).
- On the inquiring MobileMapper CE: • Run Bluetooth. • Display the properties of its File Transfer Service as explained above for the host device. • Enter the path and name of the local folder through which files will be exchanged with the host (for example the path and folder name are: \Application Data\Job547\). • Detect the host MobileMapper CE. • If required, pair the two devices (you’ll need to enter the PIN code defined in the host MobileMapper CE Bluetooth properties; see page 51).
English • To upload files from the inquiring device to the host, tap and hold the stylus on a blank area (i.e. not on a file icon) within the Bluetooth Manager window. When a dotted circle appears, remove the stylus and then select Add file in the pop-up menu. This opens a browser. Open the local folder containing the file you want to upload, select this file and tap OK. This starts the file transfer.
English Optimizing Accuracy General Guidelines There are five basic rules for recording MobileMapper CE rover data so as to achieve the optimal accuracy: 1. Allow the receiver to have full “view” of the sky the entire time a job is open, not just when logging data to a feature. There are three things you can do to improve signal reception: • While you do not need a survey-grade external antenna for sub-meter accuracy, using one will yield better accuracy in all environments.
English Recording Data for Post-Processing There is one additional rule for optimizing MobileMapper CE accuracy when recording rover data that will be differentially corrected by MobileMapper Office in post-processed mode: All features must be logged while the receiver is continuously tracking at least 5 satellites with a PDOP less than 4 for at least 20 minutes.
59 English If the period of continuous lock is less than 5 minutes, the SBAS-corrected position may be more accurate. When recording a job for post-processing, the receiver records GPS measurements the entire time the job is open – not just when you’re recording data into a feature. Therefore, you do not need to record each feature for more than 20 minutes. Each feature has to be recorded during a portion of the job file where you maintained lock on the satellites for at least 20 minutes.
English Appendices Updating MobileMapper CE OS Firmware The current version of MobileMapper CE Operating System (OS) firmware can be downloaded from ftp.magellangps.com in the /Mobile Mapping/MM CE/Firmware/OS Firmware/ folder. 1. Turn on MobileMapper CE and either attach it to external power or make sure that there is at least a 25% charge in the battery (tap Start>Settings>Control Panel>Power). 2. Copy the OS firmware file with the *.nbx file extension (e.g., NK_x_xx.nbx) to an SD card.
9. Tap in the upper right of the Windows screen to exit back to the desktop. 10.Turn off the receiver by tapping , then Suspend and then OK button. 11.After a few seconds, MobileMapper CE’s green LED will shut off. You may then press the power button to turn the receiver back on. 12.You may verify that the new OS firmware has been successfully uploaded by tapping: >Settings>Control Panel 13.Scroll down to the Thales System Info icon. Double-tap on this icon.
English 4. Copy all the files extracted from the GPS firmware zip file from your PC to the MobileMapper CE’s SD card using ActiveSync’s Explore utility. The Explore button is located in Microsoft Active Sync window’s taskbar (third button from the left). 5. Some versions of ActiveSync require that you click the Explore utility’s Folders button (in the task bar) in order to copy/paste files from one location to another. 6.
When first using your MobileMapper CE, and because there is no recent almanac file available yet in the unit, the internal GPS receiver (or Mission Planning if used at that time) will use a default almanac file stored in its protected memory. After receiving GPS satellites for about 12 to 25 minutes, the internal GPS receiver will be able to create a new almanac file. This file will be stored in the “Windows” folder and named as follows: almyy.
English Assessing MobileMapper Beacon Reception Quality As long as the green lock indicator light on MobileMapper Beacon stays on, you can be certain that MobileMapper CE can readily deliver a DGPS solution using the incoming correction data packets from MobileMapper Beacon. You can verify this by running the GPS Status utility (see Viewing Current GPS Status on page 14; In the status bar at the bottom of the screen, “Differential GPS” should be displayed and the indicator light should flash in blue.
SNR SNR<10 dB 10 20 dB DGPS Data Reception Quality Very Critical; DGPS mode steadiness is very unlikely. Good but critical; if signal deteriorates, even slightly, MobileMapper CE won’t be able to maintain DGPS mode. Excellent; there is signal level “in reserve”, which means even if the signal slightly deteriorates, DGPS mode will be maintained.
