| Summary: | The article presents a comparative analysis of the accuracy of GNSS (Global Navigation Satellite System) measurements in RTK (Real-Time Kinematic) mode using correction services from GeoNet, 1Yocto, EUREF (European Reference Frame) and EGNOS (European Geostationary Navigation Overlay Service) networks in single and VRS (Virtual Reference Station) modes. The coordinates obtained with the CHCNAV i50 and Trimble R4 receivers were compared with the reference values determined by the Trimble S6 robotic total station. The assessment was based on the calculation of horizontal and vertical errors, as well as the Root Mean Square Error (RMSE) for each of the networks. According to the results of the study, the GeoNet network demonstrated the lowest RMS (0.026 m total error), which confirms its high efficiency in real conditions. The 1Yocto and EUREF networks showed worse results, and EGNOS was the least suitable for high-precision geodesy due to significant vertical and plan errors. Additionally, the results of PPK (Post-Processed Kinematic) were analysed, but due to the short duration of fixation, these data are considered only indicative. The results obtained show the potential of commercial RTK networks to achieve centimetre accuracy, which meets the requirements of modern surveying practice. |
