Abstract
A vehicle tracking unit may include a vehicle position determining device, a wireless communications device, and a controller cooperating with the wireless communications device and the vehicle position determining device for determining vehicle position information and for periodically sending vehicle position information to a monitoring station. Furthermore, the controller may vary a period between successive sendings of vehicle position information based upon a triggering event. By way of example, the triggering event may include a vehicle speed exceeding a threshold, a period change signal from the monitoring station, and/or the passing of time. Additionally, the controller may include a memory for storing the vehicle position information, and the triggering event may include the memory reaching a predetermined capacity.
