CARRIER-PHASE MULTIPATH CORRECTIONS FOR GPS-BASED SATELLITE ATTITUDE DETERMINATION

Angela K. Reichert and Penina Axelrad

Abstract: Multipath errors in GPS carrier-phase data dominate the error budget for short-baseline applications such as static and kinematic relative positioning and vehicle attitude determination. This paper demonstrates the high degree of spatial repeatability of these errors for a spacecraft environment and describes a correction technique, termed the sky map method, which exploits the spatial correlation to correct measurements and improve the accuracy of GPS-based attitude solutions. Examples of CRISTA-SPAS satellite results are presented.
