Abstract The coastal marine gravity field is not well modelled due to poor data coverage. Recent satellite altimeters provide reliable altimetry observations near the coast, filling gaps between open ocean and land. We show potential of recent for modelling using least squares collocation technique. Gravity prediction error coast better than 4 mGal. anomalies are validated with sparse shipborne...

In this study, a sexaxial figure of the Earth was created using randomly distributed 6400 control points on geoid, which generated by EGM2008 gravity model. The shape ellipsoid is defined its six orthogonal axes. To construct new geometric figure, eight triaxial ellipsoids were fitted to Cartesian coordinates in each octant geoid least squares method. Its origin constrained coincide with centre...

Numerous global gravitational field models have been derived from the GOCE satellite gravitational gradiometry mission. They differ by the harmonic analysis approach and the time span covered by the measurements. The quality of individual solutions is assessed by validating the global gravitational field models with respect to independent datasets. Global gravitational field models based on the...
