Abstract

An inventory tracking system includes a tracking device coupled to a transport structure that is designed to carry items. The tracking device includes a processor as well as several modules operatively connected to the processor for determining the location of the transport structure. The tracking device determines location using a short-range communication module when the tracking device is within a storage facility. When outside of the storage facility, the tracking device determines a location of the transport structure using a satellite navigation module. A mobile communication module is used to determine the location of the transport structure if neither the short-range communication module nor the satellite navigation module is successful.
