GPS Vehicle Tracker

GPS Vehicle Tracker: "This application note describes a simple way to track the location of a vehicle and identify whether it has an authorized driver based on 1-Wire technology. This has many uses such as finding stolen vehicles, creating automatic vehicle logs, and managing a fleet of trucks and buses. An example of how to do this is described. It uses a Garmin GPS 35 GPS receiver, a Siemens TC35 GSM module, a DS1990A iButton, a Parallax Basic Stamp (BS2P) microcontroller, and, of course, sample source code."
