为实现GEO空间慢旋目标特定面的连续观测，提出了一种天基监视受控绕飞轨道设计方法. 首先建立了目标、天基平台相对运动模型，研究了空间任意自旋轴下的期望相对轨道模型，设计了单周期受控绕飞模型和多周期螺旋接近受控绕飞模型，应用时间约束的多脉冲控制实现平台受控绕飞，仿真分析了不同绕飞半径、不同脉冲数、不同绕飞周期下的受控绕飞轨道，最后提出并验证了多周期螺旋接近受控绕飞策略. 结果表明，基于GEO空间自旋目标姿态变化的受控绕飞的相对轨道设计，能够实现目标特定面的连续指向观测，相关仿真结果和结论对实际工程应用具有一定的参考意义. 

Trajectory Design and Simulation of Space-Based Surveillance Controlled Flying Around for GEO Slow-Spinning Space Target

A method of controlled flying around of space-based surveillance was proposed to observe continuously the specific surface of GEO slow-spinning space target. Firstly, a relative motion model of target and space-based platform was established. And then, analyzing the expected relative orbit model of arbitrary spin axis, a single cycle controlled flying around model and a multi-cycle spiral approaching controlled flying around model were designed. Time constrained multi-pulse control was used to realize controlled flying around. Finally, the controlled flying around orbit with different flying radius, different number of pulses and different flying periods was simulated and analyzed to provide and verify a multi-cycle spiral approaching controlled flight strategy. The results show that, by mapping the attitude changes of GEO slow-spinning space target to the design of relative controlled flying around orbit, the continuous surveillance of the specific surface can be realized. The simulation results and conclusions can provide a significant reference for engineering application.
