This article discusses the results of the measurements of position accuracy in 3D space for a UAV object using real-time kinematic measurements of the GPS system. The aim of the research presented in the work was to determine all three components (x, y, z) describing the location of the UAV object during the flight and making comparative characteristics using the PPS navigation service. Comparison of the differences between the two methods showed that the obtained results are characterized by a 95% of certainty. The results obtained in this experiment showed the accuracy of height measurement using the PPS GNSS system at a level of 10-80 centimeters. The results of this study also indicate that kinematic measurements can be very useful in the work of the air traffic controller and engineers of other specialties involved in position determination using satellite techniques. The article also presents a mathematical model defining the process of determining the position of a UAV object during the flight, taking into account kinematic measurements. In the final part of the work, practical conclusions were presented based on the analysis and selected simulation tests.
