“女娲”计划:面向地球静止轨道的在轨服务系统

摘要

地球静止轨道(GEO)因其良好的轨道特性,在人类航天活动中扮演着重要的角色.随着GEO资源的日益紧张,GEO碎片的清理工作刻不容缓.针对GEO带的空间碎片清理,提出了名为“女娲”的GEO在轨服务计划,利用在轨回收、3D打印、在轨组装等关键技术,实现基于空间碎片的在轨制造能力,并从任务需求、任务使命、任务流程、系统组成以及卫星系统概念设计等方面,对“女娲”计划进行了系统分析.%The geostationary orbit (GEO) plays an important role in human spaceflight for its perfect orbital characteristics.With the GEO resources becoming more and more limited,it is urgent to clean up GEO debris.In view of the space debris on the GEO,a GEO on-orbit service plan "Nu Wa" is proposed to realize the on-orbit manufacturing capability based on space debris with the on-orbit recovery,3D printing,on-orbit assembly and other key technologies.Besides,the paper also makes a systematic analysis of the plan from the aspects like task demands,mission,task flow,system composition and conceptual design of satellite system.
