The invention provides a transfer track correction method and device for a long-distance retrograde track and electronic equipment. The method comprises the steps that a target nominal track is determined according to a first position difference value; wherein the first position difference value is a deviation value between a first forecast position calculated by a satellite-rocket separation actually measured orbit parameter and a corresponding position of an initial nominal orbit; the first forecast position comprises a near-moon point, and at the near-moon point, the first position difference value is determined by a forecast orbit B plane and an initial nominal orbit B plane; at the current correction point, forecasting a second forecast position of the satellite at the next correction point, and obtaining a second position difference value between the forecast orbit and the target nominal orbit according to the second forecast position; solving a second correction speed increment required by the current correction point according to the second position difference value; and correcting the operation orbit of the satellite according to the second correction speed increment. According to the method, the midway transfer deviation of the transfer orbit can be eliminated, it is ensured that the satellite is smoothly transferred to the DRO orbit, and orbit correction fuel consumption is lower.
本发明提供了一种远距离逆行轨道的转移轨道修正方法、装置和电子设备,方法包括:根据第一位置差值确定目标标称轨道;其中第一位置差值为由星箭分离实测轨道参数推算的第一预报位置与初始标称轨道对应位置的偏差值;第一预报位置包括近月点,在近月点,第一位置差值由预报轨道B平面与初始标称轨道B平面确定;在当前修正点,预报卫星在下一个修正点时的第二预报位置,并根据第二预报位置得出预报轨道与目标标称轨道的第二位置差值;根据第二位置差值求取当前修正点所需的第二修正速度增量;根据第二修正速度增量对卫星的运行轨道进行修正。本发明能够消除转移轨道中途转移偏差,确保卫星顺利转移至DRO轨道,轨道修正燃料消耗也更低。
