Abstract: The issue of improving the efficiency of the information and measurement system for air traffic control is considered
on the example of the synthesis of algorithms for the operation of the angle channel when escorting an aircraft, taking into account
the information from its onboard sensors (kinematic and dynamic parameters), which allows more accurately describing the model of
aircraft movement relative to the ATC AIS, in comparison with existing models. This leads to an improvement in the accuracy
characteristics of the angle channel. The accuracy characteristics of the AIS affect the throughput and safety of air traffic control. The
choice of state and observation models is justified, an algorithm for the operation of the angle channel is developed, computer
simulation is performed, and the results of the studied algorithms are obtained. The results of the studied algorithms can be used in
the design and development of advanced information and measurement systems for air traffic control.
