CHAMP Gravity Filed Recovery with the Energy Balance Approach: First Results
Using the principle of energy conservation has been considered for gravity field determination from satellite observations since the early satellite era, see e.g. O'Keefe (1957), Bjerhammar (1968), Reigber (1969) or Ilk (1983). CHAMP is the first satellite to which the energy balance approach can be usefully applied, now that nearcontinuous orbit tracking by GPS is available, aided by accelerometry. Simulation studies show the feasibility of the approach. One concern is the sensitivity to velocity errors. As a next step CHAMP's Rapid Science Orbits (RSO) are used. Their error level is sufficiently low to demonstrate the feasibility of the energy balance approach with real data. The accelerometer data (ACC), used for modeling the nonconservative forces, give rise to further concern.
