Abstract: The traditional on-board software architecture lacks adaptability and scalability, with a high degree of customization, significant software-hardware coupling, and slow technological evolution. To enhance utilization efficiency and intelligent application capabilities of satellite, this paper proposes an application-oriented on-board software management system for micro-nano satellite. By analyzing the research status and technical characteristics of traditional software architectures, an open software management system based on Linux is implemented, including key components and functions. In line with the system’s operational mode, we propose a method for on-board software dynamic refactoring. Furthermore, we validate the effectiveness of the software management system by a remote sensing image processing algorithm, which has a wide application prospect.
