Quasigeoid and the relation of ETRS to the Bpv system in the Czech Republic

Popis výsledku v původním jazyce

The paper deals with the development of a novel Czech quasigeoid model and the respective transformation between ETRS and the Czech vertical reference system Bpv (Baltic after adjustment) based on Molodensky's normal heights. The theoretical and numerical approach to quasigeoid modelling have been reconsidered. The determination of the disturbing potential T on the Earth?s surface is treated as the solution of the so-called gravimetric boundary value problem and thus rests on the gravity disturbances used in quality of input data. The representation formula for T has been derived by means of the Green function method interpreted for the exterior of an oblate spheroid. This leads to an integral kernel (an analogue to the so-called Hotine function) better adapted to the geometry of the real boundary. Terrain and oblique derivative effects in the boundary condition are taken into account through successive approximations and a method based on the analytical continuation. The approach enab
