Design of Intelligent Open Avionics System for LEO Satellite

Abstract

Satellite Internet system is a direction of the future development of communication satellites. As the combination of satellite communications with the Internet, it becomes an important expansion of information network construction from flat to three-dimensional. The LEO (Low Earth Orbit) constellation places intelligent and flexible demands on the Avionics system. In this paper, we propose an Intelligent Open Avionics System, which can provide a common hardware platform and open core service software to improve the processing capability of Avionics system and the dynamic adding capability of in-orbit missions. Meanwhile, a low-consumption dynamic priority-based satellite resource scheduling method is suggested to achieve optimal resource allocation by autonomously adjusting the priority under different working conditions of satellites and improve the task efficiency with limited resources.
