空间飞行器环绕进入绕飞轨道策略研究

摘要

The guidance strategy of fast forming fly-around orbit for the space non-cooperative target is investigated here. Firstly, the relative motion equations of two satellites are constructed. A sufficient condition to form coplanar natural fly-around orbit is provided as the terminal condition to ensure the chaser satellite to approach to the target. Then a circumnavigating guidance strategy is proposed by using phase plane programming method to solve the under-actuated problem. Finally, the numerical simulation results have verified the feasibility of the strategy proposed.%研究了针对空间非合作目标的快速形成绕飞轨道的制导策略.首先建立了追踪星和空间非合作目标的相对运动方程,推导出形成共面自然绕飞的充分条件并以此作为制导的终端条件；随后针对实际追踪星发动机配置方案带来的欠驱动特性,基于规划相平面轨迹的方法提出了一种环绕制导策略；最后通过数字仿真验证了该策略的有效性.
