Requirements Analyses for GPS Integrity Channel Ground Monitoring System

Young C. Lee

Abstract:	The GPS Integrity Channel (GIC) is an external monitoring system with a ground segment that continuously monitors the GPS signals and a space segment that broadcasts the GPS signal integrity status to the user receivers via geostationary satellites. This paper reports analyses of the signal monitoring concept for the GIC ground seg- ment, where it is assumed to have accesss only to the Standard Posi- tioning Service (SPS). On the basis of these analyses, requirements and functional designs, as well as algorithmic concepts for the ground station processing, are developed. An analysis is also done to determine whether the GIC can meet the malfunction warning response time requirement for nonprecision approach.
