用完全不同的方法推导出一种两颗卫星相对运动的表达式.首先,它描述的是一颗真实的卫星相对一颗在理想轨道上运动的虚拟卫星的运动,而这正是研究编队飞行所必须的;其次,这个表达式将真实卫星相对虚拟卫星的三维位置表示成虚拟卫星的Brouwer平根数及两卫星轨道根数之差的函数.据此便可以充分应用已有的关于轨道摄动的研究成果.作为一个基本模型,首先讨论了一颗真实卫星相对虚拟卫星形成椭圆型地面轨迹的飞行方式.基于轨道长期摄动的已有结果可以很容易地揭示这种飞行方式的长期变化,从而可以毫无困难地制定出轨道调整的策略.最后还研究了三颗卫星以同一条椭圆轨迹飞行的轨道设计和控制问题,该椭圆以虚拟卫星为中心.

An expression for relative motion of two satellites is derived in the very different way compared to C-W method.First, the expression represents the motion of a natural satellite related to a virtual satellite moving along an ideal orbit with arbitrary eccentricity. This is what we actually need for studying formation flying. Second, it expresses the 3D position of the real satellite related to the virtual satellite as a function d Brouwer' s mean orbit elements of the virtual satellite and the diffences between elements of two orbits. Therefore, the existing retsuting of orbit perturbation can be fully applied.
