This article presents a method of obtaining relative and global coordinates using the Global Navigation Satellite System (GNSS). Four GNSS antennas have been compared in this research. The GNSS antennas have been utilized by the Veripos and Septentrio Systems. Global Positioning System (GPS) pseudorange observations are used to obtain relative position of the GPS antennas. Relative positions are based on calculations made by the RTKLIB software. Lever arm range and bearing are used to assess accuracy of the true antenna location relative to the vessel Navigation Reference Point (NRP). The article deals with the problem of assessing the quality of real-time positioning equipment. Comparing results of the raw position calculation with the physical measurements shows the usefulness of the real – time position monitoring.
