Kombinirani izračun EUREF GPS-kampanj na območju Slovenije : Combined Solution of the EUREF GPS Campaigns of the Territory of Slovenia
Abstract
In order to establish a link between the Slovene coordinate system and the unified European coordinate system, three EUREF GPS campaigns with sites on the territory of Slovenia have been realized. Results were published separately for each campaign in years 1995–1997. Comparing these results, coordinate differences of up to 5 cm were obtained at certain sites. Unexpectedly large differences lead the Surveying and Mapping Authority of the Republic of Slovenia to the decision for the recomputation of all three campaigns. The project was realized by the Geodetic Institute of Slovenia, in collaboration with the Faculty of Civil and Geodetic Engineering at the University of Ljubljana and an adviser from the State Geodetic Administration of the Republic of Croatia. The expert support was also kindly offered by the Federal Agency for Cartography and Geodesy, Frankfurt on the Main, Germany. The recomputation was completed in August 2003. The result are new, better quality coordinates of all the sites determined in the EUREF GPS campaigns on the territory of Slovenia. This is an important step on the way to a new national coordinate system. An outline of the data processing strategy and result analyses are given. The purpose of the paper is the provision of information in terms of realization of the recomputation and consequently with the change of the ETRS coordinates in a high quality geodetic network of Slovenia.
