GPS
The GPS tab is used to specify the protocol, communication, and other settings of your GPS receiver.
![]() |
Protocol
Choose the protocol of your GPS receiver’s output, that is, NMEA 0183, Earthmate, PLGR, SiRF, or TSIP.
The default is NMEA 0183.
Port
Choose the COM port that your GPS receiver is connected to on your device.
The default is COM1.
Baud
Choose the baud rate of your GPS receiver’s output.
The default is 4800.
Advanced serial port parameters
Tap to open the Advanced Serial
Port Parameters dialog box. Specify additional communication settings for the
serial port used to connect your GPS receiver. For most GPS receivers, it should not
be necessary to specify these additional serial communication settings.
The advanced serial port parameters are described in the next section.
Find GPS
Tap to search for a connected GPS
if you do not know which port on your device your GPS is connected to. Make sure that your GPS is connected and turned on (if appropriate) so the Find GPS
tool can detect your GPS. The Port and Baud drop-down lists will be updated as the
Find GPS tool searches for a connected GPS. Once a GPS has been detected, you will be
prompted to choose the GPS and use the corresponding settings.
Automatically activate
When checked, the GPS is automatically activated when an existing ArcPad map file (.apm) with a defined projection is opened.
The default is unchecked.
Show GPS activity in system tray
When checked, the ArcPad icon displayed in the system tray flashes to indicate that the GPS receiver is active.
The default is checked.
Automatically pan view
When checked, ArcPad automatically pans the map to keep the GPS position centered when the GPS is active.
The default is checked.
Log
When checked, the raw data output by your GPS receiver is logged to the GPS log file in the My Documents folder. The default name for the GPS log file is gps.log. Double-tapping Log opens the Save As dialog box for you to specify a different log file. The file name and location you choose replaces the default stored in the ArcPad preferences file (ArcPadPrefs.apx).
The contents of any existing GPS log file is cleared. The Log check box must be checked before activating the GPS for the GPS log file to be used by ArcPad. Checking or unchecking the Log check box has no effect while the GPS is activated.
A GPS log file is useful for troubleshooting GPS issues, as it shows exactly what data ArcPad has received from the GPS.
The default is unchecked.
