The main concept of the GNSS leveling is based on the simultaneous use of different kinds of heights: ellipsoidal heights from GNSS and geoidal/quasi geoidal heights from gravity measurements and global geopotential models to derive orthometric or normal heights as they result from spirit leveling.

A partir de una serie de mediciones realizadas en 2002 con el Sistema de Posicionamiento Global (GPS) en las cimas de los picos Bolivar, Piedras Blancas, Toro y Mucunuque, asi como en otros cuatros sitios cercanos a esas montanas, todas localizadas en los Andes de Venezuela, y usando un modelo Geoidal local venezolano recientemente obtenido, fueron determinadas las alturas sobre el nivel del mar de dichos picos.
The geoidal heights were split into three components, as follows:
The gravity data, such as gravity anomalies, or geoidal heights, are only one source of information used in geophysical interpretations.
This process establishes the relationship between the GPS ellipsoid surface and the geoid, which can then be used to convert GPS ellipsoidal heights to GPS geoidal heights--that is, GPS height related to global sea level.
