On the modern level of human development, more and more requirements are imposed on radio navigation systems, means and devices, which is due to increased requirements for the speed of processing information, reliability, volume and accuracy of the information received, as well as an increase in the intensity of the use of such technologies. Current situations can make the tasks of modern pilots more complicated ensuring navigational safety, which manifests itself in rather difficult conditions that require quick and correct decision. All existing radio navigation instruments and systems, regardless of their area of use, must meet such requirements as accessibility in time, space and organizational terms; accuracy of data definition; continuity of work; integrity. That is why it is necessary to determine the most effective radio navigation systems and instruments to improve navigation safety. The aim of the study is to conduct a qualimetric analysis of the main characteristics of radio navigation devices. This article analyzes Galileo, GPS and GLONASS radio navigation systems and devices. The collection of basic information about the studied radio navigation systems was carried out by studying the characteristics, technical documentation of the selected systems, as well as analyzing modern scientific sources on the research problem. During the research study, the main features of the selected radio navigation systems were described, and a comparative description of their characteristics was also presented. The analysis was carried out on the basis of the choice of criteria for evaluating acceptance methods under uncertainty. The following criteria were chosen as the criteria for the analysis: the Hurwitz, Savage, Wald, Laplace criteria. As a result of the conducted qualimetric analysis, the most efficient satellite system was chosen.
