Evaluation of GOCE/GRACE Global Geopotential Models over Greece with Collocated GPS/Levelling Observrepresentation of the Earth’s gravity field. The focus of this work is directed to the evaluation of most available Global Geopotential Models (GGMs) from GOCE and GRACE, both satellite only as well as combined ones. The evaluation is carried out over an extensive network of collocated GPS/Levelling

Evaluation of the GOCE-Based Gravity Field Models in Turkey undulations. Global gravity field model computed geoid undulations are compared with different sets of GPS/leveling-derived geoid undulations for different spherical harmonic degree expansions. High frequency components of the geoid undulations are estimated from EGM2008 and are removed from the GP

A Stokesian Approach for the Comparative Analysis of Satellite Gravity Models and Terrestrial Gravitbal geopotential model with terrestrial gravity data. A simulation test shows that the GOCE-based model can be combined into a geoid solution with an accuracy better than 3 mm for the band between degrees 90 and 180. A comparison of the GOCE-based model GOCO03S and the Canadian terrestrial gravity d
