Abstract

In 1989 a new gravimetric quasigeoid was published for the area of the Federal Republic of Germany by the present author. This solution is based on point and mean gravity data, topographic informations and a geopotential model, which were combined using the remove-restore technique in connection with the Fast Fourier Transform (FFT). In this paper extended tests of this solution are undertaken using GPS and leveling results. The comparisons based on different GPS campaigns with an extension of 10 to 800 km yield RMS differences of ±1 to ±6 cm, and prove the high potential inherent in the gravimetric and GPS/leveling techniques.
