卫星群分布式技术的研究与实现

Research and Realization of Distributed Technology on Satellite Cluster

随着航天技术的发展,越来越多的信息需在星上处理,卫星群分布式技术已成为近年来研究的热点.与地面环境不同,卫星受到体积、功耗、空间辐射等条件的限制,在卫星群建立分布式环境需掌握架构设计、操作系统、资源管理等关键技术.针对以上问题,本文先研究卫星群分布式计算与存储架构、其次研究卫星群分布式资源监控的实现过程,最后通过卫星群验证系统证明其可行性与优越性.

With the development of space technology, more and more information needs to be computed on the satellite. The distributed technology of satellite cluster hence has become a research hotspot in recent years. Different from the ground environment, the satellite is limited with some constraints such as volume, power consumption and space radiation. The key technology such as architecture design, operating systems and resource management should be grasped to establish distributed environment on satellite cluster. To solve problems above, this paper first studies the distributed computing architecture and storage architecture on satellite cluster. Then, it focuses on the implementation of distributed resource monitoring on satellite cluster. Finally, it proves its feasibility and superiority through the authentication system of satellite cluster.
