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.
