Globally referenced positioning in a shielded environment
First Claim
Patent Images
1. An apparatus for determining position that is resistant to interference and capable of use within a shielded environment comprising:
- a position receiver;
a processor operatively connected to the position receiver;
the position receiver adapted to receive satellite positioning signals;
the position receiver adapted to receive re-radiated positioning signals;
the position receiver adapted to receive pulse position modulated signals;
the processor adapted to acquire data from the satellite positioning signals, the re-radiated positioning signals, and the pulse position modulated signals and to determine a globally referenced position at least partially based on integrating and correlating the data received from the satellite positioning signals, the data received from the re-radiated positioning signals, and the data received from the pulse position modulated signals.

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.
