Verification and Evaluation Method of ILS Safe Operation State Based on ADS-B Data

Abstract

This paper proposes a verification and evaluation method of ILS safe operation state based on ADS-B. Horizontal flight information and vertical flight information can be obtained by analyzing the real-time data of ADS-B when the aircraft is approaching and landing, for verifying the reliability of ILS signals and evaluating ILS equipment operating status by historical data. The purpose of this method is to assist the real-time ILS reliability verification and historical data acquirement and statistical analysis, to determine the fluctuation of the guide signal at a certain moment, to provide a scientific data basis of the real-time monitoring and decision implementation of the flight calibration test.
