摘要

A novel method for detecting GPS satellite clock excessive acceleration faults is presented, which allows users of GBAS to detect clock faults even during extended outages of the Differentially Corrected Positioning Service (DCPS). The method is based on monitoring residuals of the acceleration solution computed from carrier-phase measurements. To demonstrate its function, the algorithm is verified using data collected from a hardware receiver. Because the algorithm is designed to react to rare events, a simulation is used to study algorithm performance in the presence of a fault. The proposed method represents a significant reduction in ranging error, by two orders of magnitude for the same probability of missed detection, as compared to conventional Receiver Autonomous Integrity Monitoring (RAIM).
