ABSTRACT:
A method, apparatus and system for globally referenced positioning in a shielded environment includes integrating and correlating information from a UWB receiver, a GPS receiver, and a bent-path GPS receiver adapted to extract a GPS radio frequency wave from a heterodyned GPS signal. The method, apparatus, and system is resistant to interference and can be used in a shielded environment such as indoors or behind a line-of-sight barrier.
