Abstract:
Automatic Dependent Surveillance-Broadcast (ADS-B) signal reception based on low-orbit satellite constellation system has gradually become an important technical method of airspace traffic management. In this paper, by establishing the satellite receiving ADS- B system model, the relationship between the system performance and the ADS-B receiver sensitivity and other factors is theoretically analyzed. Theoretical analysis and simulation show that the terminal position update rate of the ADS- B receiving system based on the low-orbit satellite constellation is mainly determined by the receiving performance of the ADS-B receiver, the number of overlapping coverage of the constellation system and the number of terminals within the beam coverage; When the frame performance is better than 1×10-1, increasing the overlap coverage of the constellation system is the most effective way to improve the system capacity.
