GPS settings
Tap / Settings / System / System Information / Wireless to check that GPS is installed.
COM2 is the dedicated hardware port for the built-in GPS (COM1 is dedicated to the external 9-pin).
The GPS is compatible with applications that accept the NMEA position information using a default
baud rate of 38400.
To change GPSsettings if you use multiple GPS-aware applications:
Note – If you are using only one GPS-aware application, these settings do not need to be changed.
Tap / Settings / System / GPS. The tabs available are as follows:
l Access: The GPS Intermediate Driver (GPSID) allows multiple applications to access the GPS
receiver. If the Manage GPSautomatically check box is not selected, the GPSID is disabled.
l A-GPS: use assisted-GPS to improve time-to-fix.
l Programs: Programs that use GPS need to know which COM port to use to access GPS data.
When using more than one GPS-aware application, the same GPSID port must be used in each
application. Ensure that the COM port on the GPS-aware application(s) is set to the same GPSID
port as shown in the Programs tab of the GPS applet. The program port must be a different
port than the hardware port. By default, the GPS program port is COM3 and should not be
modified unless directed by Technical Support.
l Hardware: COM2 is the hardware port dedicated for the built-in GPS. Verify that COM2 is
selected. The internal GPS communicates at 38400 baud by default. If it has been modified by a
third-party program, adjust to match the receiver baud rate.
Note – Some GPS-aware applications may not communicate over GPS program ports.
Using SatViewer
SatViewer provides information such as your current longitude, latitude, elevation, how many GPS
satellites are visible and the quality of the computed coordinates.
To open SatViewer, tap / SatViewer. To begin monitoring GPS satellites, select the GPS tab
and tap Connect to GPS.
Note – External GPS receivers, Bluetooth GPS receivers or other external GPS devices are not supported and
may not work correctly with SatViewer.
