Satellite gravity gradient grids for geophysics
The Gravity field and steady-state Ocean Circulation Explorer (GOCE) satellite aimed at
determining the Earth's mean gravity field. GOCE delivered gravity gradients containing
directional information, which are complicated to use because of their error characteristics
and because they are given in a rotating instrument frame indirectly related to the Earth. We
compute gravity gradients in grids at 225 km and 255 km altitude above the reference
ellipsoid corresponding to the GOCE nominal and lower orbit phases respectively and find …
