New Concept for Independent GPS Integrity Monitoring

Young C. Lee

Abstract:	Monitoring of the GPS signals-in-space status for integrity, with a fast response time, is essential if the system is to be used by civil aviation for nonprecision approach guidance. One alternative to provide such a monitoring function is to employ an independent monitoring system with a few ground-based signal monitors to cover a region and a satellite-based integrity broadcast channel. This paper introduces a new decision concept for accepting or rejecting a GPS signal for navigation in the independent monitoring system. Performance of the new concept is evaluated in terms of the probability of alarms against position error protection level, which are two important parameters for any method of integrity,
