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

Abstract

The invention relates to a predicting method for an aircraft track based on 4D. An air traffic control system comprises a data communication module, a monitoring data fusing module, an onboard terminal module and a control terminal module, wherein the monitoring data fusing module is used for realizing the fusion of air traffic control radar monitoring data and automatic related monitoring data and supplying real-time track information to the control terminal module; and the control terminal module comprises two sub-modules for generating a conflict-free 4D track before flight and generating a 4D track in medium / short period of flight. According to the systemic predicting method for the aircraft track, the control terminal module is adopted for processing flight planning data, and a hidden Markov model is utilized to generate the 4D track, so as to realize the analysis for the potential traffic conflict under the air traffic condition. According to the method provided by the invention, the safety of the air traffic can be effectively increased.

Description

[0001] This application is the application number: 201510008041.X, and the invention name is "An Air Traffic Control System" Aircraft Trajectory Prediction Method", the filing date is: January 7, 2015, a divisional application of the invention patent application. 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 congestio...
