Assessment of marine geoid models by ship-borne GNSS profiles

Geodesy and Cartography, 2017
Even though the entire Baltic Sea is included in previous geoid modelling projects such as the NKG2015 and EGG07, the accuracy of contemporary geoid models over marine areas remains unknown, presumably being offshore around 15–20 cm. An important part of

Pengaruh Densitas Topografi Terhadap Ketelitian Model Geoid: Studi kasus Pulau Sulawesi

Journal of Geospatial Information Science and Engineering
Penentuan model geoid teliti penting untuk mendapatkan tinggi ortometrik dari tinggi Global Navigation Satellite System (GNSS).   Salah satu faktor yang mempengaruhi ketelitian model geoid adalah densitas topografi.

Determination of the Quasi-Geoid of Xinjiang and Tibet Areas and the Normal Height of Mt. Everest Based on EGM2008

Terrestrial, Atmospheric and Oceanic Sciences, 2011
The normal height H* is the height above the quasi-geoid, which coincides with the geoid in the ocean but slightly deviates from the geoid in terrestrial areas. In Mainland China, the height datum system is based on the quasi-geoid.

The Spherical Harmonic Representation of the Geoid

Geomatics
Global Gravitational Models (GGMs) describe the Earth’s external gravitational field by a set of spherical harmonic (Stokes) coefficients. These coefficients are routinely used to compute the geoid model, while disregarding the upper continental crustal (

Geoid determination using airborne gravity vectors

Earth, Planets and Space
In traditional airborne gravimetry, the vertical component of the gravity vector is used as an approximation of the measured magnitude of the gravity vector, which enters the determination of the local geoid.
