| | GNSS RTK receivers used for precise geodetic measurements and positioning enable the calculation of point position coordinates based on the reception of signals from different GNSS constellations: GPS, GLONASS, Galileo, BeiDou, which are owned by different countries or the union of countries. Standard ISO 17123-8 specifies and defines field procedures to be adopted when determining and evaluating the precision of GNSS RTK field measurement systems and their ancillary equipment. This paper will present the procedure and comparative results of field testing of the Leica GS18 measuring system using the same GNSS Network of permanent stations while receiving corrections from multiple or single GNSS constellations. The purpose of the experiment was to analyse the precision of the 2D position of rover points of the test polygon, depending on the number and arrangement of satellites from different GNSS constellations. The testing was carried out in an urban environment. The results represent actual conditions in the field and indicate the potential influence of surrounding objects on the quality of RTK positioning. |
