Satellite Tracking
Satellite Tracking : Takes advantage of space-age communications to track the whereabouts of a truck. The communications are actually facilitated by two orbiting satellites. One serves as the communications link between driver and dispatcher, the other as the vehicle tracker. Two-way communications between the truck driver and dispatcher are routed through the first satellite. The second tracker satellite gives a fix on location. A truck dispatcher can determine a truck's location by measuring signal length from the tracker satellite to a communications terminal mounted in the truck cab
