In this paper, a novel design of a satellite Fault-Tolerant Distributed On-Board Computer (FTD-OBC) is proposed. The FTD-OBC fault-tolerance and task migration functions rely on a distributed coordination method, which is supported by an Adaptive Middleware for Fault-Tolerance (AMFT) block. The proposed distributed computer is adaptive and reconfigures itself in case of a failure seamlessly by migrating...
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...
