In this paper a novel distributed architecture for system level Fault Detection, Isolation and Recovery (FDIR) aimed at spacecraft applications is presented. The architecture reconfigures itself in the case of a failure for seamless adaptability and operation. Two new algorithms for detection of Silent Data Corruption (SDC) errors are proposed. A selective redundancy method is employed for transient...
This paper is concerned with increasing the reliability with respect to debris impact of computing systems on board satellites using Fault Tolerant Distributed Computing. A novel adaptive middleware for fault-tolerance (AMFT) design is presented. The middleware performs failure detection, isolation and recovery and synchronizes the operation of a distributed On-Board Computer (OBC) system. If one...
