Summary:In this paper, basic concepts of GNSS systems and details of NAVSTAR GPS satellite system are explained. The special emphasis to the positioning methods, and the influence of orbital positions of satellites in GNSS positioning accuracy is given, as well as term planning GNSS measurement and software tools display that are being used for. The practical part of the work consist field work and data processing and analysis. It is chosen a certain number of points (6) with known coordinates and satisfactory accuracy. In software for planning GNSS measurements the periods of maximum and minimum number of satellites determined, and in those periods surveying of selected points is done. The data obtained by measuring process and the results are analyzed. Based on the analysis, recommendations from the standpoint of applicability software planning tool for measurements are made.
