Research on Reliability Enhancement Technology of Real-Time Operating System

In the process of continuous Intelligentization of satellite applications, it has become inevitable to equip on-board computers with real-time operating system software. Considering the complexity of the space radiation environment which mainly includes electrons, protons and heavy ions, it is of great significance to improve the reliability of the real-time operating system to achieve application programs insensitivity to radiation effects. This paper presents reliability enhancement technical scheme for real-time operation system software. Five energy pointirradiation tests were carried out in Xi'an. The real-time operating system does not have abnormal resets, which verifies the effectiveness of the reliability enhancement technology.
