Abstract

An automatic GPS tracking system consists of a GPS tracking unit secured to a person or an asset that includes a GPS receiver and a first battery powering a processor and first RF transceiver. A home base station receives the RF signal within a pre-selected proximity. A monitoring station which is in communication with the GPS tracking unit such that, if a person or asset having the tracking system secured thereon moves beyond the pre-selected proximity from a home base unit, the first transceiver RF communication signals is lost, and the processor activates an alerting device to indicate the GPS tracking unit is beyond the limited range of the home base station unit. When a second confirmation signal is not received from the home base station unit, a second battery is activated to power GPS receiver and the cellular modem to track the person or asset.
