针对传统的空气动力学模型在四维飞行轨迹预测上误差较大的问题，提出了一种基于改进的基因表达式编程（GEP）的预测模型。该模型通过历史飞行时间数据找出飞行位置、高度和过固定点时间的函数对应关系，预测下次飞行过每个固定点的高度和时间，对全程采样固定点的预测实现完整的四维轨迹预测。仿真试验验证了该预测模型更为理想，更加符合实际情形。

Against the large errors in prediction of 4-D trajectory with traditional aerodynamic models ,a new prediction model based on improvement Gene Expression Programming (GEP) was proposed .The model as function mining to obtain the function expression with the position ,height and time of fix-points from flying history .Then predict the height and time of fixpoints for next time .It could be used for the w hole voyage to make full prediction of 4-D trajectory .Experimental comparison show s the mod-el is more consistent with the actual situation .
