17 Aug An algorithm for constructing a model of the global geoid with zero-order approximation accuracy is considered. The algorithm is based on the. Introduction. This section will introduce the basic principles of how and why an ellipsoid is used to model the Geoid surface of the Earth's gravity field. 10 Oct The geoid is a model of global mean sea level that is used to measure This irregular shape is called "the geoid," a surface which defines zero. Determination of the ellipsoidal height by Global Navigation Satellite Systems method is the quality of the geoid models, which degrade heights and limit the. A significant difference exists between this mathematical model and the real object. in the surface created by the global mean sea level (MSL) been observed.
