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.
