Das freie Randwertproblem von Molodensky
Journal of Geodetic Science, 2021 Determination of the geoid with a high accuracy is a challenging task among geodesists. Its precise determination is usually carried out by combining a global geopotential model with terrestrial gravity anomalies measured in the region of interest along with some topographic information.

The Quasigeoid: Why Molodensky Heights Fail [PDF]
, 2023 AbstractAny height system has two constituents: A reference surface upon which all heights are equal to zero, and a prescription for how observed heights and height differences will be related to that surface. That prescription is typically formulated with reference to Earth’s gravity field, but in this contribution, we will use the concept of metric ...

On the Consistency between a Classical Definition of the Geoid-to-Quasigeoid Separation and Helmert Orthometric Heights. [PDF]
Sensors (Basel), 2023 It is acknowledged that a classical definition of the geoid-to-quasigeoid separation as a function of the simple planar Bouguer gravity anomaly is compatible with Helmert’s definition of orthometric heights.

Journal of Geography Environment and Earth Science International, 2021 The non-availability of ellipsoidal heights of local geodetic Datums has made it necessary for the application of ellipsoidal heights transformation models to the available global ellipsoidal heights to obtain their respective theoretical heights in ...

The effect of remote zones on the accuracy of evaluating the Molodensky [PDF]
, 1976 An analytical method is presented for determining the error in computing the gravity anomaly from the Molodensky integral if geoidal undulation data in remote zones are neglected.

Discussion on the orthometric height realization [PDF]
Geodesy and Cartography, 2012 In the theory of the orthometric height, the mean value of gravity along the plumbline between the geoid and the earth's surface is defined as the integral mean. To determine the mean gravity from the gravity observations realized at the physical surface
