Sažetak
In this paper a review of the past gravimetric measurements over the territory of Croatia and the description of the establishment of the Basic Gravimetric Network (BGN) of the Republic of Croatia are given. This network consists from totally 42 points; 6 absolute gravimetric points (0. Order Gravity Network) and 36 relative gravimetric points (I. Order Gravity Network). Zero series of measurements in BGN have been done using two relative gravimeters Scintrex CG-3M and one Scintrex CG-5 in the period between June and August 2003. In the continuation, the processing and the adjustment of those measurements, as well as the analysis of the results for the final gravity values are reported, based on the conducted adjustments. In order to get a reliable transformation between Potsdam and IGSN71 gravimetric datum, the transformation parameters have been calculated and their error estimates given.
