Abstract The existing methods are analyzed for receiving and processing data from a GNSS receiver obtained on a moving car in the form of messages in degrees of latitude and longitude and converting them into meters. An accuracy assessment was carried out to determine the location and movement of machinery using various methods. The method is proposed for data processing and obtaining the longitudinal profile of the road, the car velocity (mode) using a GNSS receiver (according to the parameters of the velocity and altitude of a moving object on the surface of the Earth). It is revealed that the considered foreign methods of location determination in relation to the CIS give significant discrepancies (up to 2 times), which is associated with the use of various systems of reference points in the CIS and abroad, including in cartography, electronic maps. It is established that when estimating the distance covered by the difference in the displacements of two points of the positioning projections and their summation for small quantization increments (8–20 m, depending on velocity and frequency), the considered methods can lead to a discrepancy of up to 30–47 %. It is proposed to use the simplified linear formula lat_m = 112297,6196∙Ddec lat, lon_m = 63215,444 Ddec lon in the territory of the Republic of Belarus when determining relative distances and linking to maps. It has been found that to obtain a longitudinal profile of the road, depending on the distance covered, the mode of movement of vehicles, military machinery, unmanned aerial vehicles, it is more correct to use GNSS receiver data on velocity and altitude, providing a minimum error (0.15 %), which is confirmed by the nature of the change h = f(l), υa = f(l) and indicates the correctness of the proposed method. Also, when modelling the car movement, it is necessary to take into account road factors affecting the driving mode.
