On a combined use of satellite and terrestrial data in refined studies on Earth gravity field: Boundary problems and a target function

Popis výsledku v původním jazyce

The purpose of the presentation is to discuss the combination of terrestrial and satellite gravity field data and to show its spectral and space domain interpretation. Potential theory is of key importance in this field. However, the problems discussed are overdetermined by nature. Therefore, methods typi-cal for the solution of boundary-value problems are used together with an optimization concept, target functions and regularization techniques. Two cases are treated. They are motivated by the use of asatel-lite-only model of the gravity field of the Earth or by data coming from satellite missions (especially GOCE) in common with terrestrial gravity measurements. For the results reached in the spectral domain summation techniques are applied in orderto find the interpretation of the results in terms of kernel (Green?s) functions related to the particular combination scheme. This enables to show the tie between the global and the local mod-elling of the gravity field. In order to dem
