Sažetak
Determining the user’s position using Global Navigation Satellite System (GNSS) data depends on the presence of errors in the satellite part of the system, random errors, errors in the system environment, and user errors. If we systematically neglect and do not apply the error reduction algorithms and process the available input position records of the observed GNSS satellites identically, the differences in position accuracy can be attributed to the effect of the geometric position of the satellite expressed by the GDOP (Geometric Dilution Of Precision) coefficient. At the same time, the number of visible satellites is observed considering the applied elevation mask. The results indicate that the differences in the geometric positioning of the satellites and the orbits lead to a non-uniform accuracy of the user’s position, which depends on the latitude of the user’s position. The key parameter is the elevation mask, whereby increasing the number of visible satellites does not contribute to increased accuracy
