Research on Method of On-Orbit Evolution for Aerospace Control Software

This paper summarizes the development of software evolution technology. Based on the fundamental concepts of software evolution, we deeply analyzed the motivation and evolution process of the on-orbit evolution for aerospace control software. Five key technologies in on-orbit evolution of aerospace control software are emphasized, including architecture modeling, unified description of adaptive elements, construction of on-orbit evolution knowledge base, on-orbit evolution requirement perception and event identification mechanism, and policy-based adaptive decision-making mechanism. In conclusion, we point out the challenges and development trends of the on-orbit evolution of aerospace control software.
