摘　　要：在两航天器近距离交会中,常采用基矢量理论。但是在远距离交会时,使用传统方法计算误差较大。采用基矢量理论和过渡坐标系理论相结合的方法来解决上述问题。提出的方法首先采用基矢量法,对交会时间进行优化。在得出交会时间的前提下,将交会过程分成三个阶段,并且以时间间隔作为控制量,来重新建立交会坐标系,并推导了迭代方程。最后,可以不考虑地球摄动的相对运动方程作为参考模型进行验证,仿真计算证明,文中提出的方法与传统方法比较位置误差很小,有很好的工程实用性。The theory of primer vector is widely used in short distance rendezvous for two vehicles. But when the distance is long, the error of the traditional calculation method is big. To solve the problem, in this paper both of primer vector and transitional coordinate system are used. The method get the precise time by four - impulse rendezvous first. Then the whole rendezvous is compartmentalized three phases, and the transitional coordinate system is reconstructed by time. The iterative equation is given. At last, compared to the relative motion equation without perturbations, this method is good enough for the practical engineering.
