摘要
随着飞行流量的增加,提高空域利用率及安全性需要更精准的预测航迹作为飞行管理的参考依据。基于地空实时信息交换技术AIDL,将影响航迹预测精度的不确定性因素气象模型考虑在内,提出改进模型,并建立相应的4D航迹预测算法,运用AIDL语言实现多类势态信息、多用户有效分享、空地、空空、地地的协同决策。通过仿真计算及建立交互模型,考虑实际气象条件的飞行轨迹,将AIDL运用到实时交互通信中,对于提高轨迹预测的精度以及提高空域利用率具有实际应用价值。
The 4D trajectory prediction is a foundation technology of flow management and ATC automation. With the increasing flight traffic, the more accurate trajectory prediction is needed for Airspace utilization and Flight safety. This paper based on Realtime ground- air exchange technology that Aircraft Intent Description Language （AIDL）, Converted realtime weather information to parameter which affecting the flight, and to establish the corresponding 4D trajectory prediction model. Through simulation and correlation analysis, the flight path which considering the actual meteorological conditions have more practical value.
