摘　　要：部署在地球同步轨道的通信卫星的造价昂贵,轨道资源稀缺,在轨卫星执行任务的影响范围广,可靠性要求更高,需要设计有效的备份手段,以确保卫星可靠执行任务.利用目前部分在轨运行的航天器实际寿命高于设计寿命的实际情况,设计“理论服役期满”同步轨道通信卫星离轨备份方案,针对卫星离轨后的管理需求,分析坟墓轨道备份的可行性,提出服役期满同步卫星离轨备份的应用模式,研究临时服务模式和补网重构模式下的约束条件和备份效能,为各同步轨道卫星在轨备份设计提供参考,提高同步轨道通信卫星在轨运行的应急响应能力.The communication satellites deployed in geosynchronous orbit are expensive and the orbital resources are scare.The influence range of on-orbit mission is wide and the reliability requirements are high.Based on the fact that the acutal life of some spacecraft in orbit is generally higher than the design life,it designs the theory life of geosynchronous orbit communication satellite off-orbit backup scheme and studies the using mode,constraint conditions and backup efficiency of off-orbit satellite,which can provide reference for the on-orbit backup design other geosynchronous orbit satellites.
