摘要: 飞行器的星历积分不可避免涉及中心天体的选取问题。“嫦娥二号”卫星在拓展试验期间处于弱引力区,文章针对拓展试验期间的轨道状态,从受摄运动二体问题角度分析得出适宜选取太阳作为中心天体。进而结合真实力模型情况,使用行星星历表计算行星产生的摄动力,从理论上推导得出在忽略小天体摄动的前提下,由于摄动天体同时对中心天体和飞行器产生摄动作用,以地球为中心天体产生的摄动力类似于潮汐力,而以太阳为中心天体则不然,因而更适宜选取地球作为中心天体计算轨道运动问题

Abstract: The selection of integration center is inevitably involved in the orbital spacecraft calculation, so it is for Chang'e 2  (CE-2)  mission. During its extended mission, CE-2 satellite was placed in the Sun-Earth L2 libration orbit near the weak gravitational area. The selection of the integration center was discussed with theoretical analysis. According to the perturbed twobody problem, it is appropriate to choose the Sun as the integration center. While the force model was calculated by using the JPL DE ephemeris without considering the perturbation of small planets, the Earth would appear to be a better choice.
