Improvements in the Earth gravity field model have other obvious applications to the geodetic sciences. To adapt from the Executive Summary of the US National Research Council Report on Satellite Gravity & The Geosphere [1997], the GRACE gravity model will enable:

  • an improved reference frame for defining position coordinates
  • better calculation of orbits for geodetic satellites (including altimetric & interferometry missions) without the problem of residual geographically correlated orbit errors
  • a more accurate equipotential surface to which land elevations can be referenced
  • the adjustment and datum correction of a vast array of regional terrestrial, marine and airborne gravity survey data.

The GRACE mission is jointly implemented by NASA and DLR under
the NASA Earth System Science Pathfinder Program.
