Linux based redundant system for satellite on-board computer

摘要

In this paper, we present results of our research on designing and implementing a prototype of a redundant system for satellite on-board computer using Intel Galileo. The system is designed to simulate fault tolerant system on satellite on-board computer. The triple modular redundant system implemented on a Linux-based operating system that installed on the on-board computer. Simulation is carried out by testing various possible scenarios. By using this redundant system, the system reliability level is improved in terms of fault tolerance of on-board computer hardware. The testing results show that the system will keep carrying out its mission as long as the fault does not occur on all three on-board computers at the same time.
