Initial Design of Micro-Satellite Formation Flying

使用两体相对运动的Hill方程进行小卫星编队飞行队形的初步设计,给出了编队飞行中各绕飞小卫星的轨道要素确定过程。以空间圆形编队为例,在未考虑摄动的情况下,通过仿真验证了设计的有效性。

Hill equations are used here to describe the relative movement of two bodies. By taking advantage of the equations, it is possible to design the micro-satellites formation flying. This paper develops a new method to determine the initial condition of the relative movement. Based on the relationship between the earth-centered inertial system and relative system, we can obtain the absolute initial position and initial velocity of deputy satellites. In order to estimate the validity of this method, here we take the circular relative orbit as an example. Without the consideration of perturbation, the result of simulation shows that performance of this method is good for design of micro-satellite formation flying.
