Numerical simulations for the non-linear Molodensky problem [PDF]
Studia Geophysica et Geodaetica, 2013 We present a boundary element method to compute numerical approximations to the non-linear Molodensky problem, which reconstructs the surface of the Earth from the gravitational potential and the gravity vector.

A Nash–Hörmander iteration and boundary elements for the Molodensky problem [PDF]
Numerische Mathematik, 2013 We investigate the numerical approximation of the nonlinear Molodensky problem, which reconstructs the surface of the earth from the gravitational potential and the gravity vector.

Partially-conformal variations of the Standard Molodensky datum transformation [PDF]
Boletim de Ciências Geodésicas, 2022 : Standard Molodensky is a recognised method of transforming coordinates between geodetic datums. Although less accurate than some other methods, it has the merit of being direct.

Improved estimates for the linear Molodensky problem [PDF]
Journal of GeodesyThe paper deals with the linearized Molodensky problem, when data are supposed to be square integrable on the telluroid S, proving that a solution exists, is unique and is stable in a space of harmonic functions with square integrable gradient on S.

Error propagation for the Molodensky G1 term [PDF]
Journal of Geodesy, 2019 Molodensky G terms are used in the computation of the quasigeoid. We derive error propagation formulas that take into account uncertainties in both the free air gravity anomaly and a digital elevation model.

On the Applicability of Molodensky’s Concept of Heights in Planetary Sciences [PDF]
Geosciences, 2018 Geometric heights, defined with respect to a geometric reference surface, are the most commonly used in planetary studies, but the use of physical heights defined with respect to an equipotential surface (typically the geoid) has been also acknowledged ...
