Testing Kinematic and Dynamic Orbit Determination Approaches for GOCE Mission with Data From CHAMP and JASON-1 Satellites

Purely kinematic and dynamic approaches for precise orbit determination (POD) of Low Earth Orbiting (LEO) satellites were developed based on spaceborne GPS measurements and zero- and double-differencing with or without ambiguity resolution. Here, we presents results for two LEO satellites, CHAMP and JASON-1, that orbit the Earth at very different altitudes, namely 410 km in the case of CHAMP and 1335 km in the case of JASON-1. In order to provide CHAMP kinematic orbits over a long time span for the various groups that perform gravity field determination, results of the CHAMP kinematic and reduced-dynamic orbit determination are presented for the period of one year (day 70/2002-70/2003).
