The paper presents an analysis of measurements obtained for three selected GPS receivers and the conclusions drawn from them. As part of the conducted research, the author collected data intended to determine the criteria for satellite selection for positioning used by selected GPS chipset manufacturers.Navigation applications based on the GPS system are becoming increasingly important in surface transport, both in terms of public transport and private road network users. On one hand, this is due to the fact that at present there is practically no alternative to this system, as similar systems (GLONASS, GALILEO) are not yet fully operational and do not provide satisfactory positioning accuracy everywhere on the globe. On the other hand, the systematic development of technique and technology causes a constant decrease in production costs and an increase in the availability of receivers for this system to an ever-wider circle of users.
As part of the conducted research, the author attempted to answer the question of what criteria should be followed in order to select a GPS receiver that ensures the smallest positioning error. With a significant number of devices available on the market, it is becoming increasingly difficult to decide which of the receiver parameters will be key to obtaining measurement accuracy sufficient for a specific purpose. In the literature [e.g. (…)
