EVALUATION AND COMPARISION RECENT GLOBAL GEOPOTENTIAL MODEL IN SERBIA

SGEM International Multidisciplinary Scientific GeoConference EXPO Proceedings, 2013
Within this paper the evaluation and comparison test of a series of global geopotential models (GGM) is shown using available terrestrial data from the territory of Serbia. Using the model of European Improved Gravity 6C2 (EIGEN-6C2), then the model of Gravity Observation Combination 02S N 03S (GCCO02S and GCCO03S) as well as the model of the Earth ...

Assessment of recent global geopotential models based on the Auvergne test area data

Engineering Research Express, 2022
Abstract The gravitational field is important for many natural phenomena related to earth dynamics, especially mass transport. Its precise determination is essential for earth sciences such as geodesy, geophysics and oceanography. Determining the earth’s gravitational field is the same as determining the earth’s potential.

Regional improvement of global geopotential models using GPS/Leveling data

Studia Geophysica et Geodaetica, 2019
Global geopotential models are widely used in the remove-compute-restore technique for local gravity field modeling. In this paper, a method for regional improvement of global geopotential models using GPS/Leveling data is presented. The part of the spherical harmonic expansion degrees that can be subject to the regional improvement is determined ...

Global to Local Moho Estimate Based on GOCE Geopotential Model and Local Gravity Data

2015
Collocation approach has been applied to get a global Moho model in spherical approximation based on a GOCE geopotential model. A simple single layer model, with known density contrast, has been considered and a linearized relationship between the spherical harmonic coefficients of the anomalous potential and those of the Moho depth has been derived ...

Comparison and evaluation of the new Russian global geopotential model to degree 360

2000
A new Russian global geopotential model was created with the use of detailed gravity data, satellite tracking and altimetry data. Through the research and operations executed, the global Earth gravity field model GAO-98 with the resolution level corresponding to the geopotential expansion into spherical harmonics up to 360th degree has been developed ...
