On the Combination of Terrestrial and Satellite Data in Refined Studies on Earth Gravity Field

Popis výsledku v původním jazyce

The aim is to discuss the combination of terrestrial and satellite gravity field data and to show its spectral and space domain interpretation. However, the problems considered are overdetermined by nature. Therefore, methods typical for the solution ofboundary-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 a satellite-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 order to 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 modelling of the gravity field. In order to demonstrate the efficiency of the procedure results of numerical simulations are a
