GPS Integrity Monitoring and Multipath Error Distributions

Trent A. Skidmore and Frank van Graas

Abstract:	The ability to perform integrity monitoring of a differential Global Positioning System (DGPS) precision approach system is dependent upon the form of monitor used and the various noise sources acting on the reference station, the monitor, and the approaching aircraft. This paper focuses on how multipath and assumptions about its probability density function (pdf) affect the availability of the integrity monitoring function. Also discussed is a technique specified as Code/Carrier Integrity Monitoring which can be used to greatly improve integrity monitoring availability over methods employing conventional C/A-Code operations.
