The Start Tracking GPS option causes Global Mapper to look for a GPS device attached on the configured serial port (see the Setup command) and to start displaying the location of the GPS device, if found, in the Global Mapper display window.

This option is available in the GPS Menu or as a button in the GPS toolbar.

If a GPS device is found which has a valid GPS fix, you will see a triangular vessel appear in the Global Mapper view at the location reported by the GPS device. The vessel will point in the current direction of travel, as reported by the GPS device.

Start Tracking GPS at Startup

The Start Tracking GPS at Startup option will automatically start tracking GPS when the application is launched. This setting will remain for every application launch until it is unchecked.

Stop Tracking GPS

The Stop Tracking GPS command tells Global Mapper to stop tracking any connected GPS devices.
