Abstract
An integrated radio direction finding and GPS receiver tracking system. In one embodiment, a transmitter device is attached to an object to be located. The transmitter device transmits a signal. The transmitted signal is received by a portable, user-totable tracking unit. The portable, user-totable tracking unit uses the received signal to determine at least the bearing of the object from the portable, user-totable tracking unit. A position generating system is coupled to the portable, user-totable tracking unit to generate the position information of the portable, user-totable tracking unit. The bearing of the object from the portable, user-totable tracking unit and the position information of the portable, user-totable tracking unit is transmitted from the portable, user-totable tracking unit to a base station. The base station processes the bearing of the transmitter device from the portable, user-totable tracking unit and the position information of the portable, user-totable tracking unit to provide information to be employed during the location of the object.
