Google Maps with GPS Tracker

Golenfound's Google Maps with GPS Tracker is a small, free application that uploads your GPS position regularly via GPRS or 3G and then automatically updates your position on a Google Map display. You need a GPS device to use it, but you can download and try the GpsGate simulator software free for 14 days. Once you're familiar with Google Maps with GPS Tracker, you can buy a GPS device that suits your needs and configure the program to accept it.
