Michael O’Neill,Anthony Brabazon,Conor Ryant data in the parametric LSC method the data types (a) and (b) (in un-adjusted form) and after the removal of the terrain effect and the contribution of the geopotential model used, an accuracy ±4.3 mgal for gravity anomalies and ±0.04 m for geoidal heights is achieved.

The Concept and Research Progress of MASndled well by the FFT methods, to be removed while the latter, which contain significant information down to the finest resolution, present an opportunity to improve the accuracy of gravity modeling at the expense of having to use large data bases and very efficient computational algorithms.

Altimetry Based Geoid Determination at the German Processing and Archiving Facility within the ERS-1d, the sea surface topography, must be taken into account. Other existing surface data like terrestrial gravity anomalies are to be included and the estimate is to be stabilized by long wavelength geoid features, derived from satellite-only gravity field modeling.
