| 摘 要： | 因为辐射导致的单粒子翻转效应（SEU），使得微小卫星星上存储器在太空运行时其内容可能出现小概率错误，这种错误会影响计算机系统的运行和关键数据。文章阐述了“清华一号”微小卫星数据处理系统对SEU的纠错方法，分别介绍了实现（12，8）和（39，32）的汉明码纠错设计和基于FPGA的三模块冗余纠错编码方法，并分析了这些方法的工作原理和过程。

| Abstract: | Because of radiation in space environment,micro-satellite will normally experience Single Event Upset (SEU) errors in its Random Access Memory at a scale of small probability.These errors affect key data storage and the functions of on-board computer or data handling system.The error correction methods used in Tsinghua l micro-satellite are described and the details of design which implements (12,8) and (39,32) Hamming coding and Triple-Module-Redundancy coding based on FPGA are given. |
