Global Mapper provides the ability to track the position of a serial GPS device connected to your computer's serial port (or USB via a serial-to-USB convertor) or a Garmin USB GPS device connected to the computer's USB port in real-time over the top of any loaded mapping data. For serial GPS devices, the GPS device must communicate in either NMEA-0183 v2.x or Garmin binary format in order to be compatible with Global Mapper.
When tracking a GPS device, you can mark the current location as a waypoint. You can also choose to record a bread-crumb trail, or tracklog, of where you have gone.
Below is a sample screen capture of what Global Mapper looks like when tracking a GPS device over loaded data. You can see the GPS vessel location. The GPS Information dialog displays current GPS status information.
