• Finding out the distance between each satellite and using this information for reducing its own location.

• This operation of the GPS device is based on a simple mathematical principle which is known as trilateration.

• Vehicle Fleet Tracking • GPS Single Vehicle Tracking • GPS Data Logging • Real Time Tracking
