In open area the accuracy of the observer’s position obtained from the satellite navigation systems depends on a number of satellites (ls) visible above masking elevation angle (Hmin) and the geometry of systems – GDOP coefficient. In restricted area (coastal navigation, urban area) system accuracy depends on the parameters mentioned for open area and the dimensions and situated area of the obstacles additionally. The calculations were made for the observer situated on the ship sailing along the coast and in the middle of the street for different obstacles heights for Galileo system and for GPS system. Street parameters were: the street axis azimuth and latitude phi.
