GNSS observations are a common solution for outdoor positioning around the world for coarse and precise applications. However, GNSS produces geodetic heights, which are not physically meaningful, limiting their functionality in many engineering appli

Improving the accuracy of gravity models and their derived products such as Geoid models requires not only accurate airborne, shipborne, and satellite gravity measurements but also a good distribution of ground-based gravity measurements. Since terre

A precise orthometric height (H) and orthometric height difference (ΔH) determination is required in many fields like construction, geodesy and geophysics. H is often obtained from an ellipsoidal height (h) and geoid height (N) of a geoid model (GM)
