We consider the problem of spacecraft control system’s (CS) reconfiguration in cases of sensors’ and actuators’ failures. It is suggested that near-real time failure detection and localization (FDL) are provided by some control system’s subsystem. The simulation of delays and other uncertainties in the FDL subsystem’s operation is performed based on the assumption that the real failures lie within some intervals around their estimates generated by FDL subsystem. The paper may be of interest for spacecraft’s designers.
