摘要： 小卫星由于一些突出的优点正成为研究的焦点，而星载操作系统是星务管理软件指挥卫星运行的平台。当前没有专门为小卫星设计的实时操作系统，一般都是对通用嵌入式实时操作系统进行裁剪来完成，需要很大的工作量。在某小卫星设计的基础上，提出了一种星载实时操作系统内核的设计方法，其特点是：面向小卫星应用，代码少、实时性强、稳定性高。

Abstract: Small satellite is becoming important research field with its especial advantages. The onboard operating system (OS) is the platform of small satellite control software. There is no special real-time OS for small satellite recently, it wastes time to reconfigure a general real-time OS for small satellite. Based on design of a small satellite, this paper presents a design of small satellite real-time OS kernel with the characters of small satellite application oriented, small size, high real-time and stability.
