On a combined use of GOCE based models and local segments of terrestrial data in gravity field and geoid modelling
Original language description
The aim of this presentation is to discuss and to apply an optimized approach to combination of a satellite-only model of the Earth?s gravity field and terrestrial gravity measurements. Potential theory is of key importance in this field. Nevertheless, the problem discussed is overdetermined by nature. Therefore, methods typical for the solution of boundary-value problems have to be used together with an optimization concept, target functions and regularization techniques. In the first step the optimized solution was obtained as a series of spherical harmonics, thus interpreted in a spectral domain. Subsequently, summation techniques are applied in order to find the interpretation of the result in terms of an integral representation based on the use ofthe kernel (Green?s) function related to the particular combination scheme. The kernel function is a radial symmetric function and it is worth mentioning that it attains small values very quickly, that also implies the contribution of te
