SC 8000 is a digital vehicle tracking system that uses Global Positioning Satellites (GPS). The GPS satellite signals are continuously broadcast from an orbit of 20,000 miles and the SC 8000 receives those signals to calculate its location. The longitude, latitude, Unit ID and other information is transmitted via a CDMA cellular modem to a computer or control center for display on a regional map. The SC 8000 digital vehicle tracking system gets power from a direct connect to vehicle power or by a replaceable battery pack which lasts for approximately 5 days. The SC 8000 digital vehicle tracking system has a ‘Puck’ antenna that attaches with a magnet to the underside of the bumper.
