The invention provides a spaceborne GNSS receiver anti-space single event upset reinforcement system and method, the spaceborne GNSS receiver anti-space single event upset reinforcement system is installed between a GNSS antenna and an interface processing unit, and the spaceborne GNSS receiver anti-space single event upset reinforcement system comprises a main receiver processing unit and a backup receiver processing unit; the main receiver processing unit and the backup receiver processing unit have the same structure, and each of the main receiver processing unit and the backup receiver processing unit comprises a power supply processor, a first GNSS module channel, a second GNSS module channel, a third GNSS module channel and a main control processor. According to the invention, a system implementation scheme that a low-cost industrial-grade device is combined with software and hardware redundancy backup and a high-reliability anti-fuse device to control gating output is utilized, when single event upset occurs, the availability of the system can still be guaranteed through redundancy information and control measures, the reliability of the system is improved, and the service life of a satellite-borne receiver is prolonged.

    本发明提供一种星载GNSS接收机抗空间单粒子翻转加固系统及方法,所述星载GNSS接收机抗空间单粒子翻转加固系统安装于GNSS天线和接口处理单元之间,包括主份接收机处理单元和备份接收机处理单元;所述主份接收机处理单元和所述备份接收机处理单元的结构相同,均包括:电源处理器、第1GNSS模块通道、第2GNSS模块通道、第3GNSS模块通道和主控处理器。本发明利用低成本工业级器件结合软硬件冗余备份+高可靠反熔丝器件控制选通输出的系统实现方案,当发生单粒子翻转时仍能通过冗余信息及控制措施保障系统的可用性,提高系统的可靠性和星载接收机的使用寿命。
