本文研究微小卫星围绕空间站飞行 ,监视空间站运行和外观状态 ,减少航天员舱外活动。这是小卫星一种新的应用概念。文章主要研究绕飞轨道动力学和稳定性 ,以及在有摄动情况下保持绕飞轨道的控制策略。这种控制策略所消耗燃料非常少 ,根据仿真实验结果 ,绕飞卫星一个月时间仅消耗燃料的速度增量约为 3～ 4m/s。
In this paper, we study the micro-satellites flying around the space station, monitoring the operation and appearance of the space station and reducing the extraterrestrial activities of the astronauts. This is a new application concept for small satellites. The paper mainly studies the dynamics and stability of the orbiting fly-orbit and the control strategy of keeping the orbiting fly-orbit in case of perturbation. This control strategy consumes very little fuel. According to the simulation results, the rate of fuel-only acceleration around the spacecraft a month is about 3 ~ 4m / s.
