远距离轨道接近及绕飞控制技术研究

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。

Study of Long-distance Approaching and Companion Flying Technology

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-major axis to adjust the change rate of RAAN was studied;secondly,the relationship between the control time and the size of relative ellipse was given;thirdly,the method of estimating the parameter of the relative ellipse by the module difference of radial vector was put forward;finall...
