摘　　要：提出空天飞行器多余度GNC系统并行处理和故障容错设计方法:通过系统输入信息并行采集设计和GNC控制器核心模块并行处理设计提高系统信息采集和处理能力,保证GNC系统的实时性;通过系统输入和输出容错设计,使整个多余度GNC系统在处理周期内具有完备的故障容错能力.该方法具有广阔的应用前景.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 toler- ance ability. The presented method can be applied widely.
