[. . . ] The handheld outputs the following NMEA messages: GGA, GLL, GSA, GSV, RMC, VTG, ZDA. All messages are output at a one-second interval. TSIP (Trimble Standard Interface Protocol) is used by Trimble GPS applications, and is also supported by some other GPS applications. If you are using an external correction source connected to COM1 or a Bluetooth port, the corrections must be redirected to COM4. For more information, see Using real-time corrections from an external correction source, page 69. COM3 TSIP COM4 Real-time corrections Note ­ COM1 is a standard serial port that connects to external devices. For more information, see Connecting to other devices using the serial clip, page 109. GeoExplorer 3000 Series User Guide 63 5 Using the GPS Receiver Connecting to the COM port Details of how to configure different types of GPS field software to connect to the GPS COM port are as follows: GPS field software GPS Controller TerraSync ArcPad with the GPScorrect extension Configuration details Run GPS Controller. The software automatically activates the integrated GPS receiver on COM3. The software automatically activates the integrated GPS receiver on COM3. When the Trimble GPScorrect extension is installed, the extension automatically configures the ArcPad software to use the integrated GPS receiver on COM3 using the Trimble GPScorrect protocol. To connect to GPS, tap the GPS button and then tap Yes. To configure a real-time DGPS source, or to view status information, run the GPScorrect extension. To do this, tap the GPScorrect button in the Trimble toolbar. In ArcPad, tap the GPS drop-down menu and then select GPS Preferences from the drop-down menu. In the Protocol field, select NMEA 0183. Tap the GPS button Configure the software to connect to GPS on COM2 and then use the Connect or Activate GPS command. Configure the software to connect to GPS on COM3 and then use the Connect or Activate GPS command. ArcPad 7 without the GPScorrect extension NMEA application TSIP application Using the GPS field software The GPS Controller software is pre-installed on all GeoExplorer 3000 series handhelds and enables you to check the current GPS status, or to configure the integrated GPS receiver. Depending on the GPS field software you have installed, the default GPS field software will be GPS Controller, TerraSync, or the Trimble GPScorrect extension for ESRI ArcPad software. Note ­ GPS Controller duplicates the status and setup features of TerraSync software and the Trimble GPScorrect extension for ESRI ArcPad software. If one of these applications is installed, it runs instead of GPS Controller when you tap the GPS softkey in the menu bar of the Today screen. For more information about these applications, refer to the documentation for the application. Depending on the GPS field software you have installed, you can use the software to configure settings such as GPS, real-time correction, and antenna settings. You may also be able to use the software to connect to a real-time correction source, configure logging settings, and collect features. [. . . ] If the SBAS status is Waiting, the integrated GPS receiver may incorrectly change the status of the preferred real-time choice to Waiting as well. To avoid this, select Wait for realtime or Use uncorrected GPS as your second choice. Integrated SBAS is selected as the second choice source of real-time corrections. GeoExplorer 3000 Series User Guide 1 23 7 Troubleshooting Recommended GPS settings for maximum precision The following table lists some of the factors that affect the precision of your data, and describes how to minimize the effect of atmospheric interference and poor satellite geometry. B Factor Number of visible satellites Tip ­ To quickly find the recommended values shown here, move the GPS slider in the GPS Settings form to the middle (default) setting. Description The quality of your data increases with the number of satellites being used to calculate the position. To Maximize Precision You need at least four satellites to calculate an accurate 3-dimensional position. Trimble data collection software only logs GPS positions when four or more satellites are visible. [. . . ]
