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J_2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。
Aiming at the problem of long-range orbit maneuvering trajectory design and maneuvering errors in on-orbit service tasks, the deployment principle of serving spacecraft initial mooring orbit is proposed. The long-range maneuvering trajectory is designed by multi-pulse long-range maneuvering strategy. Based on this, The error analysis of long-range maneuvering orbit of service spacecraft under the influence of moving and atmospheric resistance perturbation is compared with that of double-pulse maneuvering. The simulation results show that multi-pulse maneuvering is superior to double-pulse maneuvering when the on-orbit service tasks require less time Maneuver, from the perturbation error to consider the height of the track to adjust the number of maneuvering odd times is appropriate.
