Compatibility and optimization in the combination of terrestrial and satellite gravity field data

Popis výsledku v původním jazyce

Data that come from the GOCE mission and terrestrial gravity measurements are two different sources of information on the gravity field of the Earth. The aim of this paper is to focus on their combination. The problem has an essential tie to potential theory and it is not difficult to realize that by nature it is an overdetermined problem. The aim also is to demonstrate the effect of the two different data sources on the resulting solution and to show its spectral and space domain interpretation. Methods typical for the solution of boundary-value problems of potential theory will be applied together with an optimization approach, target function and regularization techniques. In particular, the use of gravity field information contained in satellite-only models of the gravity field of the Earth or alternatively in GOCE gradiometric data in common with terrestrial gravity measurements is discussed in the paper. The compatibility of these two different data sources is given a considerabl
