The GPS signal is interfered unintentionally or manually, which leads to the GPS failure. It will cause the position error reported by the aircraft, making the pilots lose situational awareness. As a result, it will lay a great hidden peril for flight safety. In this study, the GPS signal loss analysis was carried out by using the QAR data to accurately capture loss location and period information of the signal. By displaying the analysis data on the electronic map, keeping consistent with the flight route of the aircraft, and using the longitude and latitude coordinate information of the map, it can effectively improve the efficiency and timeliness of manual patrol signal interference detection and reduce the potential safety hazards of civil aviation flight.
