Ice Mass Balance and Antarctic Gravity Change: Satellite and Terrestrial Perspectivesforward model predictions of the time-rate of change in gravity. A map-view prediction is presented for the time-rate of change in geoid, .N/. that might be retrieved from the currently orbiting gravity space craft, CHAMP (Challenging Mini-Satellite Payload for Geophysical Research and Application)

Earth Gravity Field and Seasonal Variability from CHAMPield model EIGEN-3p revealing considerable improvements in both accuracy and resolution with respect to the previous model EIGEN-2. For the year 2001, CHAMP and satellite laser ranging data of four satellites were combined to recover largest scale monthly gravity field variations that are subsequent

Energy Balance Relations for Validation of Gravity Field Models and Orbit Determinations Applied to dition to its classical form inertia forces and non-conservative force function contributions are included. If force function models and observed satellite orbits are consistent the energy balance sums up to a constant. Deviations from it can be caused either by orbit errors or by insufficiencies in

Recent Developments in CHAMP Orbit Determination at GFZhlighted. Significant developments in Precise Orbit Determination (POD) for Low Earth Orbiters (LEOs), in particular SAC-C and GRACE besides CHAMP, are described. GFZ also started to generate CHAMP-like rapid orbits for SAC-C with good accuracy. Furtheron improved LEO orbit accuracies are demonstrat
