The fast and accurate calculation of forward modelled gravitational field generated by a mass-density distribution of arbitrary 3D geometry is a prerequisite for many geodetic and geophysical applications. With a focus on the high-frequency gravity forward modelling (GFM), this thesis contributes to state-of-the-art GFM in the space domain by investigating various approximation effects, i.e., comparison and investigation of three different residual terrain modelling (RTM) variants, the effect of lateral density and the role of tree canopy effect in the RTM GFM, and by providing a new software for effective and accurate GFM.
