Abstract: A vehicle tracking system that includes a plurality of trackers, each adapted to be attached to a respective movable vehicle, and a remotely located controller for individually polling by radio each of the trackers to determine the position of the polled tracker. Each tracker includes a positioning receiver which receives satellite signals from a Global Positioning System and transmits a first positioning signal containing the position of the tracker to a micro controller unit. The micro controller unit receives the signal and transmits a second positioning signal containing the position of the tracker to a communicator. The communicator radios the second positioning signal to the remotely located controller to communicate the position of the tracker in response to a radioed polling signal from the remotely located controller.
