摘　　要：中国在“实践五号” (SJ- 5)卫星上首次应用并通过考验的星务管理系统 ,是实现卫星运行管理、自主控制、信息传送以及星地大回路操作的综合自动化系统。它是由计算机网络来协调、控制星上各种功能部件的相互联系 ,完成包括信息流、动作流、能量流的动态作业所形成的一种星载柔性服务系统。它具备有如下主要技术创新点 :构成整星多级控制 ;引入内嵌式管理执行单元 ;星上现场网络技术 ;构造硬件和软件的封装技术 ;利用商用实时多任务操作系统 ;兼容型分包遥测技术 ;复合型遥控和遥操作实现技术 ;信息多路径的冗余备份和系统重构技术 ;测试床技术 ;分级整体辐射加固技术。星务系统的应用既提高了整星自治能力 ,自动化和智能化水平 ,又分散了整星失误风险。从而 ,提高了整星级可靠性和运行功能的有效性。Satellite Keeping Operation (SKO) system first applied to chinese mission is an comprehensive automatic system which accomplishes satellite operating management, autonomous control, information transmission and ground-to-satellite loop operation. SKO is the flexible satellite-borne system which cooperates and schedules contact between various satellite components with use on-board network to perform dynamic stream tasks including information stream, action stream and energy stream. SKO has several innovations as follows: multilevel control, embedded management executive unit, field network technology, hardware/software encapsulation technology, utilization of the commercial RTOS, compatible package telemetry, compound tele-command and tele-operation technology, data multi-path and reconstruction technology, test-bed technology, radiation shielding technology, etc. Autonomous capability and intelligence of the satellite are enhanced and risk of the mission is decreased by the application of SKO to SJ-5 mission. Also top-level reliability and efficiency of mission operation are improved.
