First Claim
Patent Images
1. An apparatus for determining a globally referenced position of the apparatus that is resistant to interference and capable of use within a shielded environment comprising:
- a UWB receiver;
a GPS receiver;
a bent path GPS receiver;
an intelligent control operatively connected to the UWB receiver, the bent path GPS receiver and the GPS receiver;
wherein the bent path GPS receiver is adapted to receive a heterodyned positioning signal comprising a positioning signal heterodyned onto a UWB signal, and to deheterodyne the heterodyned positioning signal to extract the positioning signal;
the intelligent control adapted to determine the globally referenced position of the apparatus.

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.
