Abstract
In response to the urgent demands for software refactoring and upgrade on-orbit,it is brought about by the changeable development task requirements and the shorter deployment cy-cle.A spaceborne software on-orbit reconfiguration system design scheme is proposed in this pa-per.Based on RSRS422 bus and CAN bus,data receiving and multichannel data distribution framework of reconfiguration system is designed.Through protocol layer designing,proposes the method of missed data resending,the software reconfiguration system verifies and caches on the received data according to the protocol,then distributes to the target equipment needed software refactoring.Every link has check measures to guarantee the reliability of software refactoring.The experiment demonstrates the system can satisfy the command of software reconfiguration on satellites and provides reference for the reconfiguration of satellite software system design.关键词
