摘要
终端区四维轨迹预测技术是实现飞机四维制导的基础。结合当前空中交通管理体系和飞机的实际操作特性,采用过程综合法实现四维轨迹预测,具有较强的工程应用价值。建立了终端区风模型,研究了四维轨迹的解算,提出了实现四维轨迹预测的计算流程,理论上飞机到达机场的时间误差为0。
Four-dimensional trajectory prediction in terminal airspace is the foundation of the four-dimensional guidance. A process-synthesis method to realize the four-dimensional trajectory prediction is presented in this paper, which is based on the airspace management system and operational property. The algorithm mentioned above is really satisfactory form the engineering point of view. The wind model in terminal airspace is also established. Furthermore, the computation method of the four-dimensional trajectory is investigated and a realizing logic is put forward. The airplane can arrive the airport on time.
