Abstract

An automatic GPS tracking system is taught that consists of a GPS tracking unit secured to a person or an asset that includes a GPS receiver and a first battery operated a processor and first RF transceiver which emits an RF signal. A home base station receives the RF signal within a pre-selected proximity communication distance. A monitoring station which is in communication from a cellular modem or a satellite modem within the GPS tracking unit such that, if a person or asset having the tracking system secured thereon moves beyond the a pre-selected proximity communication distance from a home base unit, the first transceiver RF communication signals is lost, the processor automatically powers “on” the second battery to power up the GPS receiver and the cellular modem, and the GPS tracking unit may signal the monitoring station which displays the location of the person or asset.

The portable battery operated asset or personnel mounted GPS tracking system as in claim 1 and the automatic GPS tracking system as claimed in claim 5 and 6, wherein said GPS tracking unit further comprises a power On/Off switch and a vibrator and or a beeper in electrical communication with said processor. When said first RF transceiver detects RF signal loss, or GPS tracking unit is separated by more than a pre-selected proximity communication distance from said home base station unit and or when said communication confirmation RF signal(s) is not received from a home base station unit, said processor accordingly actuates said vibrator and or said beeper creating a vibration and or an audible alarm signal warning the person to turn ON said GPS receiver and or cellular or satellite modem circuitry power switch into ON position, using said first battery and or said second battery as power source. Or said vibrator and or beeper creating a vibration and or audible signal(s) alerting the person to turn the GPS receiver and or Cellular or satellite modem circuitry power switch into OFF position when subject or asset to be monitored enters back into communication proximity of a home base unit.

5. An automatic GPS tracking system with passive battery circuitry which comprises a, person or an asset mounted GPS tracking unit and a home base station powered by A/C or battery, said GPS tracking unit comprises,

a RF transceiver, a processor, a GPS receiver and a cellular or a satellite modem utilizing a first battery as a power source for said RF transceiver and said processor,

a power switching circuitry, controls operation of a second battery used as a power source for said GPS receiver and said cellular or satellite modem,

wherein, said GPS tracking unit RF transceiver employing said first battery as a power source is in communication with said home base station which contains;

a RF transceiver emitting at time interval RF signals, and said home base unit transmitting said transmitted signals receipt confirmation signals to said tracking unit. When said GPS tracking unit is separated by more than a pre-selected proximity communication distance from said home base station unit, said processor automatically switch'"'"'s ON said second battery power to activated said GPS receiver and or said cellular or satellite modem, to provide automatic personnel asset movement tracking/logging information to a monitoring station.
