In order to increase the safety,reliability and usability of the satellite,mission-oriented autonomous commands design of small satellites is provided after analyzing the characteristics of the small satellite commands.Several discrete commands are assembled into encapsulated batch commands.Commands condition is verified.Exception handing flow is implemented if there is exception.Satellite operation flow is simplified.Encapsulated batch commands can be started by time-programmed command or onboard events produced autonomously.Mission-oriented autonomous commands have been applied in several small satellites.%为了提高卫星的安全性、可靠性和可用性,在分析小卫星遥控指令特点的基础上,提出了面向任务的小卫星自主指令设计,把以往多条独立的间接指令组成封装系列指令,星上可以自动判断指令的执行条件,发现指令执行异常时进行处理,从而简化了卫星遥控操作.封装系列指令可以由程控指令以及星上自主产生的事件启动,文章所设计的自主指令已在多颗小卫星上成功应用.
