Research on automatic monitoring and coarse positioning technology of ADS-B signal interference source

Abstract： In this paper, an automatic monitoring and coarse localization method is proposed to identify GPS signal interference sources for the vulnerability of GPS signals in the automatic dependent surveillance-broadcast(ADS-B) data chain.The proposed technique works without changing the existing ADS-B system, just to extend the system software capabilities. Using the target data received by the ADS-B ground station, the movement trajectory of each target is tracked in real-time, developing tracking rules and algorithms,，interference analysis of GPS signals is carried out. The time, latitude, longitude and height of GPS signal loss and recovery are accurately acquired, and compared with the flight trajectory of the aircraft, and the analytical data will be displayed on the electronic map. The proposed technical mothed reduces the cost of GPS signal interference detection through flight big data analysis, improves the efficiency of manual investigation of GPS signal interference sources, and reduces the potential civil aviation flight safety risks.
