Aircraft locus prediction method

Abstract

The invention relates to an aircraft locus prediction method which is implemented by an air traffic control system. The air traffic control system comprises a data communication module, a monitoring data fusion module, an airborne terminal module and a control terminal module, wherein the monitoring data fusion module is used for realizing fusion of air traffic control radar supervision data and automatic correlation supervision data and providing real-time track information for the control terminal module; and the control terminal module comprises two submodules, i.e., conflict-free 4D track generation before flying and flight mid-and-short-term 4D track generation. The aircraft locus prediction method of such a system processes flight plan data by reliance on the control terminal module, generates a 4D track by use of a hidden Markov model and realizes analysis of potential traffic conflicts in airspace traffic conditions. The aircraft locus prediction method can effectively improve the safety of air traffic.

Description

[0001] This application is a divisional application of the invention patent application with the application number: 201510007935.7, the invention name is "Aircraft Trajectory Prediction Method for Air Traffic Control System", and the application date is: January 7, 2015. technical field [0002] The invention relates to an air traffic control system and method, in particular to a method for predicting aircraft trajectories by an air traffic control system based on 4D track operation. Background technique [0003] With the rapid development of the global air transport industry and the increasingly prominent contradiction between the limited airspace resources, in the complex airspace with dense air traffic flow, the air traffic management method that still adopts flight planning combined with interval allocation gradually shows its backwardness, as shown in: ( 1) The flight plan does not configure accurate air traffic control intervals for aircraft, which may easily cause con...

Problems solved by technology

[0005] The air traffic operation mode based on trajectory operation needs to calculate and optimize the flight path of a single aircraft at the strategic level, coordinate and adjust the traffic flow composed of multiple aircraft; trajectory to solve the congestion problem and ensure the operational efficiency of all aircraft in the traffic flow; while predicting conflicts and optimizing relief solutions at the tactical level are very dependent on the ability to accurately predict aircraft trajectories, which are currently not accurate Predict the trajectory of the aircraft in real time, and the real-time performance is particularly poor
