ILS signal quality monitoring method based on flight QAR data

Abstract

The invention discloses an ILS signal quality monitoring method based on flight QAR data. The method comprises the following steps of: determining and extracting flight QAR data; pre-processing flight the QAR data; extracting ILS related parameters from the decoded flight QAR data, and extracting flight data of an aircraft in an approaching stage and after landing from the ILS related parameters; establishing a channel structure model of a localizer based on the extracted flight data, and generating a channel structure curve; establishing a glide path structure model of a glideslope based on the extracted flight data, and generating a glideslope structure curve; and analyzing a change trend by combining the generated channel structure curve and the glideslope structure curve, and judging whether the channel structure curve and the glideslope structure curve approach or exceed a standard tolerance requirement. The ILS signal quality monitoring method provided by the invention is reasonable in setting, can timely find out the equipment faults of the localizer and the glideslope of an airport instrument landing system, has the advantage of high efficiency, and effectively improves the safety and reliability of airport operation.

AI Technical Summary

Benefits of technology

This technology allows for accurate detection of any issues with an aircraft's positioner or gaming machine during its run-up process. By collecting this data from different sources like pilots flying through their flights over multiple days at once, it becomes possible to identify potential problems before they become too serious. Its technical effect will be improved security and performance while reducing costs associated therewith.

Problems solved by technology

Technological Problem: Current methods used to monitor signals sent between pilots' ground level devices at different stages of their approach have limitations such as complex calculations required before taking appropriate actions like repositioning the device, which can lead to increased risk of accidents due to incorrect positioning of the pilot. Additionally, current techniques require expensive maintenance costs associated therewith, making them difficult to use without first finding any issues related thereto.
