A Review of Spaceborne Applications of GPS

Prem Munjal, William Feess and Mohan Ananda

Abstract:	The use of GPS signals for satellite orbit determination in real time as well as in post-processing mode has been extensively studied by many authors. Recently, many space missions have shown increased interest in implementing GPS-based orbit determination schemes. To support this increased interest, a number of GPS receiver manufachlrers have initiated development of spaceborne GPS receivers. This paper presents an overview of the spaceborne GPS receiver developments and summarizes t.h GPS receivers currently available for space applications. It also presents generic orbit determination accuracy requirements and GPS-based capabilities. In addition, the paper presents results of au orbit determination study using a specific Space Test Program (STP) space mission, Radar Calibration satellite, as an example. ‘Ihis study uses shnulated measurements with and without Selective Availability (SA) and the paper presents the SA effects on the orbit &termination accuracy.
