摘　　要：文章对半长轴、偏心率、倾角、升交点赤经相近的两航天器的远距离轨控接近方案进行了理论分析。首先研究了通过改变轨道半长轴调整航天器升交点赤经变化率,进而控制轨道法向振幅的方法;其次给出控制点的选择时机与相对绕飞椭圆大小的定量关系;然后提出采用径向矢径模之差估计远距离相对运动参数方法;最后通过"神舟七号"伴星与轨道舱的远距离接近及绕飞控制仿真对理论推导进行了验证。The orbit control technology of two long-distance satellites with similar semi-major axis, eccentric angle and inclination RAAN was analyzed. First, a new method of controlling the swing of orbit normal axis by changing the semi studied; secondly, the relationship between the given; thirdly, the method of estimating the major axis to adjust the change rate of RAAN was control time and the size of relative ellipse was parameter of the relative ellipse by the module difference of radial vector was put forward; finally, the proposed methods were verified by the longdistance approaching and companion flying simulation of SZ-7 companion satellite and orbital module.
