The american argos satellite has done experiments on the primary anti-radiation measures of cots components, and has obtained valuable experiment datas . the software fault tolerance techniques sihft provide error detection coverage of over 99 %, attracted researchers ’ attention . the experiment has demonstrated that it ’ s possible to satisfy the requirement of space applications by software techniques without special hardwares 其中,软件容错技术sihft(softwareimplementedhardwarefaulttolerance)达到了大于99%的检错覆盖率,引起了人们的关注。这项实验说明了在不需要专用硬件的情况下,使用软件技术也能达到航天应用的可靠性要求。
Because it ’ s hard to get radiation-harden hardware overseas, so the software fault tolerance techniques are significant for our national space enterprise . the computer platform of 863 plan project ” micro intelligent free-flying space robotic system ” consists of cots component . the orbit and the radiation environment of the robot are similar to ones of the argos satellite, and the system is required to have high reliability . therefore it ’ s necessary to applied the software fault tolerance techniques into the system to improve the anti-radiation capability after the techniques been verified valid 因为我国很难从国外获得辐射加固的硬件,所以,这项软件容错技术对我国航天事业的发展具有较大意义。863计划项目“小型智能飞行机器人系统”所用的计算机平台采用商用器件,其卫星的运行轨道与argos卫星轨道近似,面临的辐射环境与argos卫星相似,要求具有高可靠性。因此,小型智能飞行机器人系统有必要在验证sihft技术有效的基础上,应用软件容错技术,提高其空间抗辐射能力。
