Abstract: 4D trajectory prediction is a core technology of ATC automation system and traffic management system,which can improve the utilization and security of airspace.In this paper,a 4D trajectory prediction method is proposed.Combining the data of multi-data source radar,meteorology,flight plan and aircraft performance,the position of an aircraft at each time point is inferred by flight experience samples,and the precise prediction of flight trajectory and time is obtained.The practicability and effectiveness of the method are illustrated by the application effect in East China ATC Flow Management System and ATC Automation System. |
