一种航路4D航迹预测的方法

4D航迹预测是空管自动化系统中的一项核心技术,能够提高空域的利用率和安全性。为了在航路上快速准确的预测航空器的飞行轨迹,提出一种预测航路4D航迹的方法。首先利用Supermap制作航路网络,然后根据航空器的性能参数,推测各时间点的航空器位置,从而得到航路上航空器的飞行航迹,并通过实例进行了说明,为航迹预测提供一定参考。

A Method of Prediction of 4D Trajectory on Airway

The prediction of 4D trajectory is a core technology in the air traffic control automatic system, which is able to improve the use efficiency and security of airspace. In order to predict the trajectory of aircraft on airway quickly and accurately, this paper proposes a method to predict the 4D trajectory on airway. First of all, it uses Supermap software to make airway network, then according to the performance parameters of aircraft, predicts the position of aircraft in different time, finally gains the flight trajectory of aircraft on airway. Through the instance specification, it offers reference for prediction of trajectory.
