The paper presents the analysis of the accuracy and repeatability of determining the position of the point by the Network Real Time Kinematic (NRTK) technique using the Flächenkorrekturparameter (FKP) concept. The measurement was based on the Active Geodetic Network – European Position Determination System (ASG-EUPOS). The FKP together with Virtual Reference Station (VRS) and Master Auxiliary Concept (MAC) is the currently available method of generating corrections in NRTK technique in NAWGEO sub-service of ASGEUPOS. NRTK positioning using FKP was analysed based on Global Positioning System (GPS) and Globalnaya Navigatsionnaya Sputnikovaya Sistema (GLONASS) signals, because the combination of these satellite systems is currently a common standard. The subject of the study was a 24-hour coordinate time series with a sampling interval of 30 seconds. The collected data was compared with the precise coordinates of the measuring point by calculating the linear deviations and the mean values of X, Y and Z coordinates’ errors and mean position errors for one-hour periods. Selected measures of positioning accuracy were determined, both for threedimensional and horizontal coordinates. An analysis of selected dilution of precision (DOP) factors was also carried out. The analyses were also carried out for coordinates expressed in the horizontal coordinate system and normal heights in force in Poland due to the assessment of the suitability of FKP for geodetic measurements. The experiment showed the expediency of NRTK measurements using FKP corrections generated based on observations from the ASG-EUPOS network for determining real-time position within the territory of Poland.
