Satellite-based Automatic Dependent Surveillance-Broadcast (ADS-B) is an important technology for wide-area aeronautical surveillance. Experiments show that the surveillance performance provided by the satellite-based ADS-B system deteriorates seriously due to co-channel interference within the system. To quantitatively analyze the surveillance capacity of the satellite-based ADS-B system, a model for the satellite-based ADS-B system is developed. The collision probability and the correct reception probability of messages sent by the ADS-B transmitter of civil aircraft are theoretically derived. The update intervals of position messages and the surveillance capacity of the satellite-based ADS-B receiver are obtained. Simulation results verify the correctness of these theoretical results. Our study shows that the surveillance capacity of the satellite-based ADS-B receiver is jointly determined by the symbol error rate of the aircraft-satellite link and the required update interval of the ADS-B application subsystem.
