Summary

By means of the increased gravity measurements it is possible to compute gravimetrically the undulationsN of the geoid with regard to the used reference ellipsoid as well as the «absolute» deflection of the vertical components ξ g and η g . The quantities ξ g and η g enable us to transfer the astronomically observed coordinates of any points from the geoid to the reference ellipsoid and in this way compute without any triangulations the distances along the reference ellipsoid. And still more. With the aid ofN, ξ g and η g we can obtain a general Geodetic World System and convert the existing many systems to it.—The geoid study is no more any academical pastime, it can solve the most important problems of the practical geodesy.
