Regularization for the Gravity Field Recovery from GOCE Observations problem, which lacks stability due to the polar gaps and the downward continuation from satellite altitude to the Earth’s surface. Even in the discrete world of observations the problem is still ill-conditioned, and some kind of regularization is indispensable to provide physically meaningful solut

These measurements will be complementary with those of GOCE, which will provide unprecedented determination of the high-resolution static field. Gravity changes direc

As systems, such as EUREF etc., are basically three-dimensional, the combination and unification of continental and regional vertical datums can now be implemented. F

The non-linear datum definition problem is extended to the time domain and the optimal reference frame for a de-formable network is obtained as a geodesic line on a curved manifold in the vector space of all network coordinates, which is the union of instantaneous shape manifolds
