Simulation of Recovering Gravitational Potential Model from the Ephemeredes of CHAMP

    Graphical Abstract
    • Abstract
  • Three methods with different arc length of integration are tested in this simulation to recover gravitational potential model from the ephemoeredes of CHAMP.The results show that the regularzed method with suitable arc length of integration will improve the precision of recovering gravitational potential model.The precision of low degree harmonic coefficients from CHAMPobservations is expected 1~2 magnitude better than any current gravitational potential model.
