At the present stage of air transport development the density of the flow of aircraft increases, especially near airports, where the flux density is high. These factors make it necessary to place high requirements to information and measurement systems in terms of speed and accuracy of determining the coordinates of the aircraft.The need to increase the capacity of airports at a given high level of security is one of the main tasks of radio engineering, which directly affects the safety of life and health of passengers.The modernization of ground-based radar stations and aircraft onboard equipment, as well as the developed technologies for transmitting data from the aircraft to information measurement systems, makes it possible to synthesize a model describing the change in the aircraft azimuth acceleration in information measurement systems using full data on the kinematics and dynamics of the aircraft movement. Using discrete-address systems for transmitting information from the aircraft, the developed channels provide information that complements radar measurements, creating a full volume of data on the kinematics and dynamics of the aircraft.The paper considers a step-by-step synthesis of the model of changing the azimuth of an aircraft, taking into account its overload. The resulting expression will allow the development of mathematical models of aircraft movement that more accurately describe its movement in space. Algorithms for secondary processing of information based on the obtained expression will improve the accuracy of determining the angular coordinates of the aircraft by information and measurement systems. This fact is confirmed by the conducted research, the result of which is presented in this paper.
