Two alternative techniques for fitting the gravimetric geoid for Egypt
Contributions to Geophysics and Geodesy, 2023 In this paper, two proposed geoid fitting techniques for Egypt's gravimetrically determined geoid and Global Positioning System GPS/levelling-derived geoid are introduced. First, any errors in the available GPS stations are ruled out.

GRAVIMETRIC GEOID MODELLING OVER PENINSULAR MALAYSIA USING TWO DIFFERENT GRIDDING APPROACHES FOR COMBINING FREE AIR ANOMALY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019 We investigate the use of the KTH Method to compute gravimetric geoid models of Malaysian Peninsular and the effect of two differing strategies to combine and interpolate terrestrial, marine DTU17 free air gravity anomaly data at regular grid nodes ...

A High-Resolution Gravimetric Geoid Model for Kuwait Using the Least-Squares Collocation
Frontiers in Earth Science, 2022 A new gravimetric geoid model, the KW-FLGM2021, is developed for Kuwait in this study. This new geoid model is driven by a combination of the XGM2019e-combined global geopotential model (GGM), terrestrial gravity, and the SRTM 3 global digital elevation ...

Determination of the Orthometric Height inside Mosul University campus by using GPS data and EGM96 Geoid Model [PDF]
مجلة التربية والعلم, 2008 In the geodesy science, the heights determined by Global Positioning System (GPS) measurements are related to the perpendicular distance above the reference ellipsoid, while heights of Mean Sea Level (MSL) are determined with respect to geoid.
