Abstract: Satellite-based ADS-B system is an important technical scheme for wide-area aircraft surveillance system. To reveal the influence of co-channel interference on the surveillance performance of the satellite-based ADS-B system, a theoretical formula of the surveillance capacity of the system is proposed. Firstly, the model of satellite-based ADS-B system is given. Then, the correct reception probability of ADS-B message, the update interval of aircraft position message, and the update interval of aircraft position report are theoretically derived. Based on these equations, the surveillance capacity of the system is given. Finally, these theoretical formulas are verified by computer simulations using the Space Network Simulation (SNS) software. Our study shows that the surveillance capacity of the satellite-based ADS-B system is jointly determined by the symbol error rate of aircraft-satellite links, the symbol error rate of satellite-earth links, the number of satellites, and the required update interval of the ADS-B application subsystem.

Key words: satellite-based ADS-B system, co-channel interference, update interval of aircraft position message, update interval of aircraft position report, surveillance capacity
