Summary

Using an efficient and robust combination of a kinematic and reduced-dynamic orbit determination procedure CHAMP GPS data spanning about eleven months are processed and different aspects are addressed. Kinematic solutions are generated with and without elevation-dependent weighting of the observations in order to study the impact on the solution. GPS clock corrections with a sampling rate of 30 seconds and of 5 minutes, both interpolated to 10 seconds, are used. The orbit results are compared with the Post-processed Science Orbits from the GeoForschungsZentrum Potsdam, Germany, with orbit solutions from the Technical University of Munich, Germany, and they are validated with SLR measurements.
