在轨服务多脉冲远程机动轨道设计与误差分析

针对在轨服务任务对远程机动轨道设计和机动误差展开研究，提出了服务航天器初始停泊轨道的部署原则，采用多脉冲远程机动策略设计了远程机动轨道，在此基础上对如项非球形摄动和大气阻力摄动影响下的服务航天器远程机动轨道进行误差分析，并与双脉冲机动进行了比较，仿真结果表明，在轨服务任务对时间要求不严格时，多脉冲机动优于双脉冲机动，从摄动误差方面考虑调整轨道高度的机动脉冲数为奇数次为宜。

Multi-impulse Maneuvering Orbit Design and Errors Analysis for On-orbit Servicing

The long-range maneuvering orbit and the errors are investigated aiming at on-orbit servicing. We indicate disposition principle for the initial parking orbit of the servicing spacecraft. And then we choose multi-impulse maneuvering as the long-range maneuvering strategy, and design the maneuvering orbits. In addition, J2 and the atmosphere drag perturbations are analyzed based on the orbital maneuver. Furthermore, we compare it with two- impulse maneuvering. The results show that multi-impulse maneuver is better than the two-impulse maneuver if the onorbit servicing is not stringent with time. Moreover, odd multi-impulse maneuvering takes priority of even multi-impulse maneuvering for orbit altitude change considering the perturbation errors.
