Refined gravimetric quasigeoid for the Czech Republic

Original language description

An exclusively provided extensive dataset of gravity points on the territory of the Czech Republic and the recently released detailed digital terrain model represent, together with rapidly increasing demands for precise GNSS leveling, an important driving impulse for redevelopment of the transformation between the ETRS and the present vertical reference system Bpv (Baltic after adjustment) based on Molodensky's normal heights. From a mathematical point of view the solution of a geodetic boundary value problem has a key role in this field. The problem is formulated for gravity disturbances and the representation formula for the solution was derived by means of the Green function method. In order to refine the mathematical structure of the solution, an analogue to the so-called Hotine function was constructed for an oblate ellipsoid of revolution and subsequently used as a convolution kernel. The use of the kernel function made it possible to focus with more emphasis on the surface data
