Approximation of the Disturbing Potential through GPS measurements
Heights' determination through GPS measurements demands precise approximation for Quasigeoid's surface, if we use normal heights, or for Geoid's surface, if we use orthometric ones. Hence, estimation of the Disturbing Potential either on the Earth surface or on the surface of the Geoid is a must. At the same time, it is necessary to reduce the scope of future leveling to the minimum required for precise heights' determination through GPS measurements. This paper reviews the algorithm of approximation of the disturbing potential through GPS measurements performed on benchmarks and astronomic points.
