Surveillance Application Analysis of Beihang Aviation Satellite-1

With the rapid development of air traffic control (ATC) globalization, the space-based ADS-B system has attracted extensive research in the field of ATC because of its global coverage characteristics to overcome the blind spots of existing ground-based systems. Beihang Aviation Satellite-1 is China's first ADS-B technology verification satellite for ATC surveillance requirements and has conducted in-orbit technology verification of space-based ADS-B. This paper discusses the availability of Beihang Aviation Satellite-1 in various flight phases for civil aviation and general aviation surveillance applications with its in-orbit data, and analyzes the surveillance coverage radius and the position message update interval. The results show that Beihang Aviation Satellite-1 has the capability to provide global surveillance of civil aircraft in all phases of takeoff/landing, departure/approach and cruise, as well as the capability to track general aviation aircraft on a global scale. The maximum surveillance coverage radius is more than 2,800 km and the update interval is less than 8 seconds in different-density airspace.
