Abstract
The paper deals with the global gravity field modelling using the boundary element method (BEM). The direct BEM formulation is applied to a solution to the fixed gravimetric boundary-value problem. We present a new model of geopotential at ocean obtained by BEM using the DNSC08 global marine gravity field. This model is compared with EGM-2008. High performance computations together with an elimination of the far zones’ interactions allow a very refined integration over the all Earth’s surface. Such approach results in a high-resolution global gravity field modelling.
