Deriving orthometric height using global geopotential models (GGMs)

2016 7th IEEE Control and System Graduate Research Colloquium (ICSGRC), 2016
The purpose of this paper is to evaluate the orthometric height derived by combination of Global Navigation Satellite System (GNSS) data and global geoid height information over Peninsular Malaysia. The global geoid height information is derived from recent Global Geopotential Models (GGMs); combined and satellite-only solution.

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 ...

Spectral analysis of block averaged data in geopotential global model determination

Journal of Geodesy, 1995
The recovery of the harmonic coefficients of the anomalous potential from a geodetic quantity sampled over a regular grid is affected by the non-exact discrete orthogonality of spherical harmonics; larger errors occur for block-average quantities owing to the non-simple behaviour of the block-average operator when applied to spherical harmonics ...

Rigorous evaluation of global geopotential models for geoid modelling: A case study in Kenya

Journal of African Earth Sciences, 2022
Developing a gravimetric geoid model requires gravity data covering the whole surface of the earth. In practice, terrestrial data within a spherical cap is used, causing a truncation error, which may be minimised if the terrestrial data is combined with a Global Geopotential Model (GGM). The choice of a GGM that fits the observed terrestrial data best,

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 ...
