卫星编队飞行中的队形设计研究

目前关于卫星编队飞行的研究有显著的增加。多颗从属卫星(从星)在近距离内与主卫星(主星)组成特定的队形以完成相应的任务,是卫星编队飞行的特点及潜在优势。卫星在编队飞行时,其队形定义为以各颗卫星质心为顶点所构成的几何形状,而队形设计则是根据队形的几何形状求出各卫星的轨道根数(其中主星的轨道根数可以根据任务的要求事先确定)。基于相对轨道根数法,根据卫星相对运动方程,提出了“自然队形”的概念及队形设计的一般方法,并给出了具体的例子。

THE RELATIVE TRAJECTORY DESIGN OF SATELLITE FORMATION FLYING

Recently the research of Satellite Formation Flying (SFF) has increased significantly. The characteristic and potential advantage of SFF is that several following-satellites along with the leader-satellite in close vicinity make up a special formation to accomplish certain mission. The Relative Trajectory (RT) is defined as the geometric pattern consisting of the centroid of each satellite, and the RT design is to find out those orbit elements of each satellite according to the geometric pattern of the RT (the orbit elements of leader-satellite can be determined by performing mission first). A concept of natural formation and a general RT design method are proposed based on the Relative Orbital Element Method and the relative motion equation in this paper. An example is given.
