Abstract
An integrated radio direction finding and GPS receiver tracking system. In one embodiment, a transceiver device is attached to an object to be located. The transceiver device transmits a signal. The transmitted signal is received by a tracking unit. The tracking unit uses the received signal to determine the range and bearing of the object from the tracking unit. A position generating system is attached to the tracking unit to generate the position information of the tracking unit. The range and bearing of the object from the tracking unit and the position information of the tracking unit are transmitted from the tracking unit to a base station. The base station processes the range and bearing of the transceiver device from the tracking unit and the position information of the tracking unit to calculate the position of the object to be located.
