星载嵌入式Linux系统容错技术综述
A Review of Fault-tolerant Technologies for Spaceborne Embedded Linux Software Systems
摘要
Abstract
With the increasing complexity of space missions,the Linux operating system,due to its open-source and highly customizable nature,has gained widespread adoption in spaceborne computers.However,due to the extreme operating conditions of spacecraft such as strong radiation,extreme temperatures,and microgravity,Linux's on-orbit stability faces significant challenges.The authors provide an overview of the current status and development of Linux applications in the space sector and discuss its technical advantages and limitations in comparison with traditional spaceborne operating systems.Then,focusing on the fault-tolerance technology architecture for spaceborne Linux systems at the boot,kernel,and driver layers,they discuss the key technologies such as boot-layer trusted verification,kernel real-time modification,root file system fault tolerance,and driver-layer fault isolation.Finally,they look forward to the future development trends of onboard Linux systems in terms of combining commercial devices with fault-tolerant architecture and adaptive fault-tolerant scheduling.关键词
