According to the lunar large elliptical frozen orbit transfer orbit design method and system based on eccentricity rate vector targeting, the lifting type of a transfer orbit is determined in advance in the earth-moon transfer stage, and the earth-moon transfer orbit is selected as orbit descending launching and orbit descending arrival; it is ensured that the lunar orbit is a large elliptical frozen orbit of the far-moon point above the southern hemisphere of the moon, an earth-moon transfer orbit meeting task constraints is generated through eccentricity rate vector targeting, after the moon is captured, the amplitude angle of the near-moon point is adjusted near the far-moon point, and it is ensured that the lunar large elliptical frozen orbit is efficiently generated. And finally, according to the task requirement, applying the pulse at the perilune and transferring to the large elliptical freezing orbit of the required period.

    本发明本记载一种基于偏心率矢量打靶的环月大椭圆冻结轨道转移轨道设计方法及系统,本发明在地月转移阶段提前确定转移轨道升降类型,地月转移轨道选择为降轨发射和降轨到达,确保环月轨道为远月点在月球南半球上空的大椭圆冻结轨道,并利用偏心率矢量打靶生成满足任务约束的地月转移轨道,月球捕获后,在远月点附近调整近月点幅角,确保环月大椭圆冻结轨道高效生成。最后,根据任务需要在近月点施加脉冲转移至所需周期的大椭圆冻结轨道。
