RVSM airspace aeronautical device height holding performance monitoring system and method

Abstract

The invention relates to a RVSM airspace aircraft altitude holding performance monitoring system and method. And the system comprises: absolute altitude obtaining module; data collecting and preprocessing module; and altitude holding deviation data processing module. And the method comprises: collecting high-accuracy altitude, allowable flight altitude and actual flight altitude of an aircraft, obtaining altitude measuring reference differences corresponding to the sequence of flight trace points of the aircraft, and processing these messages to obtain the altitude holding deviation message. And the invention can obtain high-accuracy total vertical altitude deviation of the aircraft and the altitude deviation caused by artificial factors and the system altitude deviation caused by device accuracy, so as to more accurately and effectively monitor the aircraft altitude holding performance.

Description

technical field [0001] The invention relates to a system and a method for monitoring the altitude maintaining performance of an aircraft, in particular to a system and a method for monitoring the altitude maintaining performance of an aircraft in the RVSM airspace. Background technique [0002] With the continuous growth of global air traffic, airspace congestion caused by insufficient flight levels has become a bottleneck in the development of air traffic control, causing air transport companies to suffer huge economic losses. In order to make full use of airspace resources, significantly increase airspace capacity and improve utilization, countries around the world have implemented the Reduce Vertical Separation Minimum (RVSM for short). However, reducing the vertical separation standard means that the risk of collision between aircraft will increase, which will affect the safety of air transportation, so the altitude maintaining ability of aircraft will be directly relate...

Problems solved by technology

[0003] However, at present, aircraft flight altitude measurement mainly relies on ranging from ground radar stations or indirectly obtaining airborne barometric altimeter data. The measurement accuracy of the former is not high, and the latter cannot give altitude deviations, and neither can achieve high accuracy of aircraft altitude maintenance performance. Surveillance requirements, and it is impossible to analyze the reasons for aircraft altitude maintenance deviation
