Abstract

On-board Fault Detection, Isolation and Recovery (FDIR) systems are considered to ensure the safety and to increase the autonomy of spacecrafts. They shall be carefully designed and validated. Theirimplementation involves a relevant knowledge of items like functions and architectures of the system, and a fault model in relation with these items. Thus, the event-B method is well suited to correctly specify and validate on-board safety architectures. This paper focuses on the FDIR concept presentation and the use of event-B for formalising and for refining the FDIR concept.
