SYSTEM AND METHOD FOR POSITIONING IN CONFIGURED ENVIRONMENTS
First Claim
1. A system for providing physical state information within a configured environment, comprising:
- at least one emitter that emits energy within a transmission medium;
at least one interceptor that receives energy propagated through a transmission medium from the at least one emitter, wherein the interceptor is configured to process the received emissions using spectral compression to produce a set of observables suitable for physical state estimation; and
communicate the set of observables to a physical state estimator; and
a physical state estimator configured to determine at least one member of the relative physical state between the interceptor and emitter based on the set of observables received from the at least one interceptor; and
report the at least one member of the relative physical state based on the set of observables received from at least one interceptor.

Abstract
The present invention relates to a system and method for providing location determination in a configured environment in which Global Navigation Satellite System Signals are not available. In this regard, local beacon systems generate spread spectrum CDMA signals that are received by spectral compression units that derive physically meaningful observations without a requirement for correlation of the intercepted energy by means of the known spreading codes. The invention can coexist with communication assets already in place, and the design allows for self calibration, which simplifies installation and usage. The invention has utility in applications in which GNSS signals are unavailable or limited, for example, in warehouse inventory management, in search and rescue operations and in asset tracking in indoor environments.
