Název v původním jazyce

A regularized solution of boundary-value problems in combining terrestral and satellite gravity field data

Popis výsledku v původním jazyce

In this paper an optimization concept in combining terrestrial and satellite gravity field data is discussed The problems under study are overdetermined by nature. Therefore, methods for the solution of boundary-value problems are used together with an optimization approach. Two cases are treated. They are motivated by the use of satellite-only models of the gravity field of the Earth and by data coming from satellite missions like e.g. GOCE in common with terrestrial gravity measurements. For the results reached in the spectral domain series summation techniques have been used to find an interpretation in terms of Green's functions. This shows a tie between the global and the local modelling of the gravity field. To check the efficiency of the approach extensive numerical simulations have been done using simulated data derived from the gravity field model EGM96 and the normal gravity field with parameters given by GRS1980. Problems of practical nature are discussed too.
