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 method for predicting the track of an aircraft running on the basis of a 4D trajectory. The method is implemented by means of 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. The monitoring data fusion module is used for achieving fusion of air traffic control radar monitoring data and automatic related monitoring data and providing real-time trajectory information for the control terminal module. The control terminal module comprises a pre-flight conflict-free 4D trajectory generation sub-module and an in-flight short-term 4D trajectory generation sub-module. According to the method for predicting the track of the aircraft running on the basis of the 4D trajectory, the control terminal module is used for processing flight plan data, and a hidden Makov model is used for generating the 4D trajectory to analyze potential traffic conflicts of air traffic conditions. The method can effectively improve 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...
