Abstract

Considerable experience accumulated during the past decade in strategies for processing (GPS data from ground-based geodetic receivers. First experience on the use of GPS observations from spaceborne receivers for orbii determination of satellites on low altitude orbits was gained with the launch of TOPEX/POSEIDON ten years ago. The launch of the CHAMP satellite in July 2000 stimulated a number of activities worldwide on improving the strategies and algorithms for orbit determination for Low Earth Orbiters (LEOs) using the GPS.

Similar strategies as for ground based receivers are applied to data from spaceborne GPS receivers to detcrminc high precision orbits. Zero- and double-difierencing techniques arc applied to obtain kinematic and/or reduced-dynamic orbits with an accuracy which is today at the decimeter level. Further developments in modeling and processing strategies will continuously improve the quality of GPS-derived LEO orbits in the near future. A significant improvement can be expected from fixing double-difkrencc phase ambiguities to integer numbers. Particular studies focus on the impact of a combined processing of LEO and GPS orbits on the quality of orbits and the reference frame realization.
