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.
