On the target function in combining terrestrial and satellite gravity field data
Original language description
In this paper a combination of terrestrial and satellite gravity field data is discussed that in an optimal way exploits gravity field information contained in the solution of boundary problems in a close neighborhood of the Earth. The optimization restson a minimization of a quadratic functional defined on a space of functions that are harmonic in an unbounded domain, given, under some simplifications, by the exterior of the Earth. The functional attains its minimum and the respective Euler?s necessary condition is shown. It is used for constructing the function that minimizes the functional. This in principle outlines the idea of an optimal combination of the data considered in this paper. In parallel also alternatives for the target function aboveare investigated and compared.
