Abstract
Systems, methods and computer-readable medium are provided using on-board sensor data of a tracking device in addition to satellite signals to improve the determination of the location of a tracking device. In one aspect, a method includes detecting, at a server, presence of a tracking device in a high error zone; determining if geographical coordinates of a current location of the tracking device in the high error zone are within a threshold of registered geographical coordinates of the current location; activating at least one sensor on-board the tracking device when the geographical coordinates are not within the threshold; receiving displacement information of the tracking device from the tracking device; determining an updated location of the tracking device based on the current location and the displacement information; and providing an arrival alert to a destination toward which the tracking device is traveling based on the updated location.
