Abstract
A tracking device is provided. A position determiner is configured to determine a position of the tracking device. The tracking device has first and second operating modes, the first operating mode being in response to at least the absence of a data communications link with an external wireless node, the second operating mode being in response to at least the presence of communication with an external wireless node. In the first operating mode, the tracking device periodically determines its position from the position determiner and maintains a position history of the tracking device. In the second operating mode, the tracking device reduces the operations of the position determiner relative to the first operating mode. In association with the tracking device transitioning from the first operating mode to the second operating mode, the tracking device wirelessly transmits the position history.
