Gravity Field Determination for the Territory of Croatia
As a independent state, Croatia needs much better knowledge of the gravity field parameters, especially in connection with the present realization of GPS-measurements on its territory. In order to get the best possible gravity field solution in the case of really large relief variety, different kind of data — gravity anomalies, vertical deflections, satellite altimetry — has to be appropriately combined, taking also into account the topographic/bathymetric information. In this paper some preliminary results for the gravimetric geoid are presented for the first time. It’s comparison with the existing astrogeodetic solution for Slovenia and a part of Croatia is given and future possible steps described.
