摘要
由于高轨高价值卫星在轨时面临诸多威胁,探索高轨卫星平台在轨顽存技术体系(technology system of on-orbit strong survivability,TSO2S2)有利于提升平台在轨生存能力。针对这一情况,系统地定义了TSO2S2内涵,从分析威胁源出发,建立以告警和防护为手段的顽存技术体系。首先,将8种威胁分为被动型和主动型,分别阐述威胁机理,采用定性和定量结合的方法分析其损伤效应。其次,提出天地一体的平台防护方案,设计兼顾空间碎片、激光等5类威胁的综合告警设备。最后,系统总结了防护技术方法,为高轨卫星平台提升在轨安全性提供参考。
As high value geostationary earth orbit(GEO)satellites are under a range of threats,it is helpful to improve the survivability of satellite bus by exploring the technology system of on-orbit strong survivability(TSO2S2).Focusing on this,the concept of TSO2S2 is defined systematically.A protection system including warning and safety protection sub-system is built after the main threat sources are figured out.Firstly,8 threats are divided into active type and passive type.The threat mechanisms are analyzed and the damage effects are evaluated using qualitative and quantitative methods.Secondly,an integrated space and terrestrial warning scheme is proposed and the equipment is designed which enabled 5 types of threats to be alarmed,including space debris,laser,et al.Finally,the protection technology and methods are summarized systematically,which can provide reference for the GEO satellite platform to improve the orbit safety.
