介绍一种将姿控系统和星务管理系统融为一体的设计思想 ,它节约了星载机资源 ,提高了系统信息处理的实时性 ,很好地体现了小卫星的质量轻、体积小、成本低的优势。对姿控系统的硬件组成、卫星的飞行模式和控制策略、星务管理软件的体系结构和总体设计思想、姿控软件和星务管理软件的接口设计等内容做了重点讨论。 This paper introduces a design idea that integrates attitude control system and satellite service management system, which saves the resources of satellite carrier and improves the real-time performance of system information processing. It reflects the advantages of light weight, small size, Low cost advantage. The hardware composition of the attitude control system, the flight mode and control strategy of the satellite, the architecture and overall design concept of the satellite management software, the interface design of the attitude control software and the satellite management software are emphatically discussed.
