Publication number: 20140062781Abstract: The present invention relates to a system and method using hybrid spectral compression and cross correlation signal processing of signals of opportunity, which may include Global Navigation Satellite System (GNSS) as well as other wideband energy emissions in GNSS obstructed environments. Combining spectral compression with spread spectrum cross correlation provides unique advantages for positioning and navigation applications including carrier phase observable ambiguity resolution and direct, long-code spread spectrum signal acquisition. Alternatively, the present invention also provides unique advantages for establishing the validity of navigation signals in order to counter the possibilities of electronic attack using spoofing and/or denial methods.Type: ApplicationFiled: May 17, 2013Publication date: March 6, 2014Applicant: Loctronix CorporationInventors: Michael B. Mathews, Peter F. MacDoran

Publication number: 20110234454Abstract: 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.Type: ApplicationFiled: February 17, 2011Publication date: September 29, 2011Applicant: LOCTRONIX CORPORATIONInventors: Michael B. Mathews, Kenn L. Gold, Peter F. MacDoran
