This research presents the results for analyses done to five geopotential global models
(GGM), comparing them with ground data from GNSS and leveling in heterogenic zones …

The availability of many high-degree Global Geopotential Models (GGMs), namely
EGM2008, EIGEN-6C4, GECO, SGG-UGM-1, SGG-UGM-2, XGM2019e_2159, and …

The geoid error, computed from EGM08, is unrealistically large due to the continuation of the
spherical harmonic coefficient errors down to the surface of the reference ellipsoid. In this …

After launching the GOCE (Gravity Field and Steady-State Ocean Circulation Explorer)
which obtains high-frequency gravity signal using a gravity gradiometer, many research …

The main purpose of this paper is to estimate the zero-height geopotential value for the
Argentinean Local Vertical Datum (LVD). The methodology is based on the computation of …

The GOCE satellite mission has significantly improved the results obtained with the previous
satellite missions CHAMP and GRACE. Using GOCE data satellite Global Geopotential …

There are several techniques for determining geoid heights using ground gravity data, the
geopotential models, the astro-geodetic components or a combination of them. Among the …

Within the frame of the Elevation project, recently acquired collocated GPS/Leveling
observations over trigonometric benchmarks (BMs) have been used for the evaluation of the …

The objective of this study is to assess the recent GRACE and GOCE release 5 (R5) global
geopotential models (GGM) in Canada. For the evaluation of the GGM against GPS …

Since ESA released to the public domain the first Global Geopotential Model (GGM) based
on GOCE satellite mission data, an extensive validation/evaluation of those models has …
