Monitoring system of airspace use provides continuous automated detection, tracking, identification of aircraft and unmanned aerial vehicles present within the airspace above a megapolis and adjacent regions, as well as recording of information on violation of current flight requirements with further output of data to the data consumers involved.

The system is based on the principle of joint use of advantages of main technologies for surveillance over air objects: primary radar surveillance, multilateration and automated dependent surveillance.

This approach ensures detection and tracking of all types of air objects, including the ones not equipped with on-board transponders.
