Abstract

The invention discloses an instrument landing system space signal quality analysis method based on airborne DAR data, which includes the following main steps: data acquisition step S1: through the customized data acquisition program module of the flight status monitoring system ACMS software to achieve acquisition of the aircraft Carrying DAR data; data decoding step S3; extracting heading data step S6: extract heading DDM value, longitude and latitude data from the decoded airborne DAR data; heading analysis step S7: analyze the heading DDM value, longitude and latitude data , analyze and obtain the quality of the localizer space signal; extract the glide data step S8: extract the glide DDM value, latitude and longitude, and height data from the airborne DAR data after the decoding; glide analysis step S9: analyze the glide DDM value, latitude and longitude , height data, and analyze the space signal quality of the slide deck. The invention has the beneficial effects of realizing fast and reliable evaluation of the space signal quality of the measuring instrument landing system, which not only saves costs but also improves efficiency.

Description

technical field [0001] The present invention relates to the technical field of control or regulation systems of non-electrical variables, in particular to the control of the position, course, height or attitude of vehicles in the air, such as autopilots, and more specifically to the three-dimensional position of instrument landing systems Simultaneous control of or course (G05D 1 / 10), the present invention particularly relates to an instrument landing system signal-in-space quality analysis method and system based on airborne DAR data. Background technique [0002] The following briefly introduces the prior art related to the present invention, so as to facilitate the understanding of the present invention. [0003] Instrument Landing System ILS [0004] In China's civil aviation control system, the instrument landing system ILS (Instrument Landing System) is the standard navigation aid system for "non-visual" approach and landing. It provides the heading signal for the a...
