Today the combination of Stokes' formula and an Earth gravity model (EGM) for geoid determination is a standard procedure. However, the method of modifying Stokes' formula …
In a modern application of Stokes' formula for geoid determination, regional terrestrial gravity is combined with long-wavelength gravity information supplied by an Earth gravity model …
Abstract Global Navigation Satellite System positioning of gravity surveys permits geoid computation via Hotine's integral. A suite of modifications is presented so that the user can …

When regional gravity data are used to compute a gravimetric geoid in conjunction with a geopotential model, it is sometimes implied that the terrestrial gravity data correct any …

Computational stages of a new high-resolution 5 mm quasigeoid model for Estonia are explained. Certain requirements for the quality and coverage of gravity data in the context of …
Any errors in digital elevation models (DEMs) will introduce errors directly in gravity anomalies and geoid models when used in interpolating Bouguer gravity anomalies. Errors …
