| Abstract: | Single event protection is more and more important in the development of spacecraft. This paper firstly analyzes the characteristics of the impact of single event soft errors on the spacecraft, and then establishes a criticality model for evaluating the impact of a single event soft error on spacecraft. Finally, a weakness identification method and the steps of single event protection are presented, which results provide an objective basis for improving the single event protection design. |

| Keywords: | Spacecraft Single event effect Soft error Reliability |
