DETERMINATION OF THE GEOID HEIGHTS BY ANOMALIES OF POTENTIAL DEDUCED FROM A NORMAL GRAVITY FORMULA

Abstract

The geoid height - defined as the distance between surfaces of the geoid and the Earth spheroid is usually determined by Stokes’ expansion, using sattelites gravity anomalies. In this paper, we determined the geoid heights by Bruns’ formula, using anomalies of potential (perturbating potential). But the anomalies of potential provided by sattelite doesn't connected with the classical normal gravity formulae, which are using in some countries. In the previous paper [8], a method of determining the normal gravity potential from any classical normal gravity formula has been presented. Applying this formula, we have computed the perturbating potential relative to Cassinis’ normal gravity formula (1930) and the geoid heights by Bruns’ formula and constructed the geoid map.
