Title:
METHOD FOR RECEIVER AUTONOMOUS INTEGRITY MONITORING AND FAULT DETECTION AND ELIMINATION
Document Type and Number:
WIPO Patent Application WO2005027283
Kind Code:
A3
Abstract:
A method for detecting and identifying a faulty measurement among a plurality of GPS measurements, obtained by a GPS receiver with respect to a plurality of satellites in view of the GPS receiver, determines whether the plurality', of GPS measurements include a faulty measurement. In response to a determination that the plurality of GPS measurements include a faulty measurement, the method identifies a satellite contributing the faulty measurement by computing a correlation value associated with each of the plurality of satellites, and selecting a satellite associated with a highest correlation value as the satellite contributing the faulty measurement.
