Comparative Analysis of Integrity Decision for a GPS Integrity Channel

Young C. Lee

Abstract:	One alternative to provide integrity monitoring of GPS signals is to employ a GPS Integrity Channel (GIC), consisting of a few ground-based signal monitors to cover a region, and a satellite-based integrity broadcast channel to provide real-time GPS signal status. This paper provides a quantitative comparison of three alternative concepts to be used in the GIC for deciding whether a GPS signal should be used in the navigation solution when performing non precision approaches. These concepts are analyzed and compared in terms of position error protection level, false alarm probability, and detection probability.
