Abstract
In order to determine accurate orbits for the global positioning system (GPS) satellite constellation, a software system called MSOP (multi-satellite orbit processor) has been developed. MSOP is a software program which determines the GPS multi-satellite orbits simultaneously using pseudorange data. This paper describes methods and strategies specific to the precise orbit determination of GPS satellites, with special emphasis placed on force modeling of the solar radiation pressure and y-bias, and reports experiments in which the satellite constellation accuracy of sub-ppm, required for the precision in geodetic applications, is confirmed. The orbit accuracy was evaluated from analysis of P-code pseudorange data collected by the Cooperative International GPS Network (CIGNET), being primarily based on a direct comparison with the precise ephemerides generated at the Naval Surface Warfare Center(NSWC). It was demonstrated that the accuracy of GPS satellite orbit determination method using pseudorange data is better than 0.5 ppm, namely 10 m for the satellites on the average. 15 refs., 5 figs., 9 tabs.
