Abstrakt EN: Regional recovery of the disturbing gravitational potential from satellite gradiometry data is the subject of this contribution. We exploit the mathematical apparatus of the integral formulas which transform the disturbing gravitational potential onto disturbing gravitational gradients in the local north-oriented frame (LNOF). The integral formulas are rigorously decomposed into two effects, i.e., the near and distant zones. Then only the effect of the near zones is sought for by inverse problem, while the distant zones are synthesized from a global gravity field model (GGM) with spectral weights given by truncation error coefficients.
