The primary objective of the 1-cm geoid experiment in Colorado (USA) is to compare the
numerous geoid computation methods used by different groups around the world. This is …

Forward gravity field modelling requires high accurate determination of the topographic
potential on the surface of the Earth's ellipsoid. Since the topography is recently known with …

In the framework of the IAG African Geoid Project, an attempt towards a precise geoid model
for Africa is presented in this investigation. The available gravity data set suffers from …

Bathymetry data over lake areas are not included in the current and previous NGS (National
Geodetic Survey) geoid models. Lake surfaces are simply treated as land surfaces during …

Launches of the CHAMP (CHAllenging Minisatellite Payload) and GRACE (Gravity
Recovery And Climate Experiment) satellite missions have produced a new generation of …

This thesis attempts to answer the question: What is the accuracy of GOCE satelliteonly
global geopotential models in Egypt? The answer of this question is included in two steps …

This article concerns the development of gravimetric quasigeoid and geoid models using the
geophysical gravity data inversion technique (the GGI method). This research work was …

This study aims to estimate the effect of the resolution of the available Digital Height Models
(DHMs) on the reduced gravity anomalies and the final computed gravimetric geoid. The …

The available gravity data set for Africa consists of land point gravity data as well as
shipborne and altimetry derived gravity anomalies data, but suffers from a lot of significant …

In the framework of the remove-restore technique, the residual field should be, more or less,
unbiased and have a small variance. Hence, a high-degree reference geopotential model …
