摘要：The paper presents the research results of availability of defined coordinates error value,determined with the use of ASG-EUPOS network,during surveying measurements of a test railroad section. The experimental measurements with four sets of receivers GNSS were carried out on Kościerzyna-Kartuzy railway route,in February this year. The research program assumed installation of four sets of phase receivers GPS System 1200 (Leica),which used Active Geodetic Network EUPOS to calculate coordinates. The sets were installed on board of railroad platform driven by an electric trolley. The measurements were carried out by Real Time Kinematic method with NAWGEO surface correction. As a result of measurements,there were almost 40,000 coordinates determined for each of the antennas. The paper presents the procedure of measurements and the model of mathematical calculation of availability of defined coordinates error value,which was used in results analyses. It also presents the functions and border values of availability,based on the assumption of the decision threshold between the ability and disability states amounting to 10 cm. Moreover,the article indicates cognitive areas of further directions of experimental research.
