Abstract: A parallel process and faulttolerance method is presented for the multiple redundancy GNC system of aerospace vehicle. Via parallel design, the input information acquisition ability is improved. The processing ability can be improved by parallel processing of GNC controller core module. Based on the fault tolerant design of system input and output, the redundant GNC system has complete fault tolerance ability. The presented method can be applied widely.

Key words: aerospace vehicle, multiple redundancy, parallel process, faulttolerance
