A microprocessor monitors vehicle/personal position by way of coordinates obtained from Navstar Global Positioning System. Upon activation, through sensing unauthorized access to a vehicle or a change in its position, the microprocessor identifies itself to a central dispatch office and alerts the same to the nature of the disturbance. The system periodically updates vehicle location by way of digital signals sent to the central dispatch station by way of a cellular mobile telephone system. The central dispatch office can interrogate the microprocessor via the telephone link by addressing its unique serial number in order to obtain its position should the vehicle be stolen without activation of the micro-processor. A plurality of logic inputs and outputs are provided for accommodating conventional anti-vandalism and anti-theft detectors which may be integrated into the total protection system.
