The thesis deals with determining the coordinates of the points with GNSS surveying methods in the area located near the Slovenian - Croatian border, to be more specific in Razkrižje in Šafarsko and Gibina. To establish a coordinate basis, we have used fast static GNSS surveying and RTK measurement method. Measurements of fast static survey methods were analyzed independently twice: first, by connecting to the constantly active Slovenian GNSS network station SIGNAL in Lendava, and then by connecting to the constantly active Croatian GNSS station network CROPOS in Čakovec. We have analyzed and compared the performance of the networks of permanent GNSS stations in Croatia and Slovenia. In the first phase, we have compared the results of the post-processing of fast static GNSS measurement methods with a link to permanent refernce stations of various national networks. In the second phase we have performed RTK–surveying method GNNS on Croatian territory, first with the network SIGNAL and second time in the context of network CROPOS, and obtained results were compared. Since the measurements were carried out on permanently stabilized points with given coordinates in a coordinate system D48/GK, we have made in selected area in Slovenia a quick analysis of the quality official transformation parameters 7-parametric transformation for the area of Pomurje.
