Research on software scheduling of spacecraft real-time system

The real-time performance and reliability of on-board software is significant for the Spacecraft. Due to the expansion of space missions and the growth on complexity of on-board software, implementing the software scheduling in the distributed on-board integrated computing system becomes an important research issue. A software scheduling method is proposed for embedded real-time system of spacecraft. It aims to solve the problems of multi-node redundant scheduling of safety-critical tasks and continuity requirement of software tasks, which has good application value for increasing efficiency of on-board software scheduling.
