AI Technical Summary

Technical Problem

The lack of effective aviation radio interference early warning methods in the prior art has led to the impact of civil aviation flight safety.

Method used

By extracting the GPS level signal quality factor and integrity limit factor from the QAR data of civil aviation aircraft, we determine whether the signal is normal, and issue an early warning signal after a total of 15 times of judgment as interference.

Benefits of technology

It has realized early warning of aviation radio interference, reduced the impact of civil aviation flights and improved flight safety.

Abstract

The invention relates to an aviation radio interference early warning method. The method comprises the steps that S1, a GPS horizontal signal quality factor main driving parameter GPSHFOMCA, a GPS horizontal signal quality factor co-driving parameter GPSHFOMFO, a GPS horizontal integrity limiting factor main driving parameter GPSHILCA and a horizontal integrity limiting factor co-driving parameter GPSHILFO are extracted from QAR data of a civil aircraft; s2, if the GPS horizontal signal quality factor main driving parameter, the GPS horizontal signal quality factor co-driving parameter, the GPS horizontal integrity limiting factor main driving parameter and the GPS horizontal integrity limiting factor co-driving parameter are all smaller than 1, the signals are judged to be normal; if the GPS horizontal signal quality factor main driving parameter, the GPS horizontal signal quality factor co-driving parameter, the GPS horizontal integrity limiting factor main driving parameter and the GPS horizontal integrity limiting factor co-driving parameter are all larger than 15, it is judged that aviation radio interference exists; and S3, if it is judged that the number of times of aviation radio interference reaches 15, sending out an early warning signal.
