The positioning services provided by satellite navigation systems are now widely used in different areas of people's daily living, thus giving ground to consider them to be an important component of the global information infrastructure. The satellite radio-navigation system, also known as GPS (Global Positional System), provides high-precision positioning and speed of an object at any point, time, weather condition, as well as exact timing. The GPS system which consists of specially designed low-orbit satellites could be defined as a complex of radio-electronic devices providing positioning and speed o an object moving on surface or in atmosphere. However the development and spreading of modern satellite monitoring systems are closely connected with the improvement of the level of precision and reliability of the data received. To solve the problem it is necessary to improve the methods of an object route monitoring with the aim to save, reconstruct and analyze them. Hence it is suggested by experimental research to develop an algorithm and the Arduino microcontroller program to define geographical positioning and speed of a moving object using GPS-receiver capable to receive and process signals from the satellites of GPS space segment. The project uses GPS module capable to detect geographical coordinates, time and approximate movement speed (during the move). Every point supposes to have three coordinates, namely X, Y, Z, with X,Y as plain coordinates and Z as vertical coordinate. The discretion of getting information to be set in advance comprising one to several seconds. Due to time data a precise clock was established showing Greenwich time better known as Universal Coordinated Time. Thus, having such a set of coordinates available it is possible to register the coordinates of an object moving in a period of time. The GPS Visualizer was applied for the visual assessment of a trajectory configuration. The GPS Visualizer is bases on WGS-84 coordinate system as worldwide reference system. Therefore, the data registered by GPS-logger were projected on a map as trajectories, which could be further zoomed in/out. Ref. 7, Fig. 3
