"In the determination of the gravity field of the Earth the accuracy requirements represent a driving impulse for the use of direct and numerical methods in the solution of geodetic boundary value problems. The approach applied here for the solution of the linear gravimetric boundary value problem follows Galerkin's approximations. It is formulated directly for the surface of the Earth as the boundary of the domain of harmonicity. Thus, the accuracy of the solution is only limited by the accuracy of gravimetric data, the data coverage and the capability of the hardware. Extensive numerical simulations have been done using simulated gravity data derived from EGM96. Solutions for spherical and more general boundaries have been computed. They also show the oblique derivative effect, usually neglected in geodesy. Different function bases were used to represent the disturbing potential. The obtained solutions are compared with EGM96 in terms of potential values and gravity disturbances."@en . .
