预测轨迹在真实环境中的修正技术研究

Research of the Modified Technology about the Plan Forecast Trajectory During the Actual Operation

在4D轨迹预测模型结果实际工程应用的过程中,总是存在飞行计划预测轨迹和雷达航迹不一致的现象,通过对模型和实际数据的分析,查找计划预测轨迹的偏离因素。该文描述了实际运行过程中涉及影响预测轨迹的各类因素,分析了数据对模型的影响;并结合分析结果提出了实施过程中对计划轨迹的修正方法,该分析结果将促进4D预测轨迹在空中交通管理领域中的实施。

4D trajectory prediction model results in practical application process,there is always a flight plan and radar track forecast track inconsistencies.Through the model and the actual data analysis to find factors that deviate from the planned trajectory prediction.This paper describes the process involved in the actual operation of the various factors affecting forecast track,analyze data on the impact of the model.Combined analysis of results of the implementation process of the plan trajectory correction method,the results will contribute to 4D trajectory prediction in air traffic management in the implementation.
