Design and Implementation of GPS Interference Analysis System Based on QAR Data

As the most accurate navigation device in flight, GPS plays an extremely important role in the take-off, cruise, and landing phases. Statistics on GPS interference incidents reported by airlines for the past five years found that there were 28 interference incidents in 2016, and then showed an upward trend year by year, with 351 incidents occurring in 2020. In order to solve the impact of GPS interference on flights, this paper combines WEB and ETL technology to propose a GPS interference analysis method, which promotes the investigation of GPS interference points. Through practical applications, it can achieve a more accurate effect of locating the interference source.
