Integrated radio direction finding and GPS receiver tracking system
First Claim
1. A method for locating an object comprising the steps of:
- attaching a transceiver device to an object to be located,transmitting a signal from said transceiver device, when said transceiver device is activated;
using said tracking unit to activate said transceiver device to transmit said signal,receiving said signal transmitted by said transceiver device at a tracking unit,determining from said signal received at said tracking unit the range and bearing of said object from said tracking unit,generating position information of said tracking unit using a position determining system coupled to said tracking unit,transmitting said range and bearing of said object from said tracking unit and said position information of said tracking unit from said tracking unit to a base station, andprocessing at said base station said range and bearing of said transceiver device from said tracking unit and said position information of said tracking unit to calculate the position of said object to be located.

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.

12. An object locating system comprising:
-
a transceiver device attached to an object to be located, said transceiver device transmitting a signal therefrom to a tracking unit, when said transceiver device is activated by the tracking unit; said tracking unit having an activator to activate said transceiver device such that said transceiver device transmits said signal, said tracking unit receiving said signal transmitted by said transceiver device, said tracking unit including a tracking component for determining the range and bearing of said transceiver device from said tracking unit, said tracking unit further including a transmitter integral therewith, a position determining system attached to said tracking unit, said position determining system generating position information for the location of said tracking unit, and a base station communicatively coupled to said tracking unit, said base station receiving said range and bearing of said transceiver device using the transmitter of said tracking unit and said position information for the location of said tracking unit when such information is transmitted from said transmitter of said tracking unit, said base station further including a position processor for calculating the position of said object to be located using said received range and bearing of said transceiver device from said tracking unit and said position information for the location of said tracking unit. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
