The calculation of topographic (and iso-static) reductions is one of the most time-consuming
operations in gravity field modelling. For this calculation, the topographic surface of the Earth …

Various tasks in geodesy, geophysics, and related geosciences require precise information
on the impact of mass distributions on gravity field-related quantities, such as the …

We present an accurate method for the calculation of gravitational potential (GP), vector
(GV), and gradient tensor (GGT) of a tesseroid, considering a density model in the form of a …

The harmonic correction (HC) is one of the key quantities when using residual terrain
modelling (RTM) for high-frequency gravity field modelling. In the RTM technique, high …

Topographic and isostatic mass anomalies affect the external gravity field of the Earth.
Therefore, these effects also exist in the gravity gradients observed, eg, by the satellite …

The analytical computation of the full gravity tensor from a polyhedral source of
homogeneous density is presented, with emphasis on its algorithmic implementation. The …

The study of the gravity field of arbitrary polyhedral bodies of homogeneous density has
provoked a series of publications over the last decades. Some of the researchers …

This study demonstrates that in mountainous areas the use of residual terrain model (RTM)
data significantly improves the accuracy of vertical deflections obtained from high-degree …

We assess the new EGM2008 Earth gravitational model using a set of 1056 astrogeodetic
vertical deflections over parts of continental Europe. Our astrogeodetic vertical deflection …

At the beginning of the twenty-first century, a technological change took place in geodetic
astronomy by the development of Digital Zenith Camera Systems (DZCS). Such instruments …
