即插即用模块化卫星体系结构研究

摘要

Plug and play modular satellite is a new satellite system combining the modular plug and-play technique with the satellite platform technique. It is an important way to implement the Operationally Responsive Space(ORS). The conception of plug-and-play modular satellite is pres ented,and the applications of plug-and-play technique in space missions are analyzed in the paper. The architecture of plug-and-play modular satellite is summarized, including function module par- tition, plug-and-play standard interface, satellite platform bus and system software. The function decomposition is analyzed on the basis of traditional satellite subsystems, and the function module partition method of plug-and-play modular satellite is proposed. The research result can provide a theoretic reference for the development of plug and play modular satellite technique in China.%即插即用模块化卫星是模块化即插即用技术与卫星平台技术相结合的新型卫星系统，是实现空间快速响应的重要途径。文章介绍了即插即用模块化卫星的概念；分析了即插即用技术在航天任务中的应用；概括了即插即用模块化卫星的体系结构，主要包括功能模块、即插即用标准接口、卫星平台总线和系统软件。在传统卫星分系统划分的基础上进行功能分解，提出了即插即用模块化卫星功能模块的划分方案。文章的研究结果可为中国发展即插即用模块化卫星技术提供理论参考。
