ESEO spacecraft: FMEA (Failure Mode and Effects Analysis) and FDIR (Fault Detection Isolation and Recovery)

The purpose of the present doctoral activities concern the reliability of electronic systems and their fault tolerance. The main field of application whose is addressed this research is the aerospace industry, in particular it has been developed around the E.S.E.O. (European Student Earth Orbiter) spacecraft/mission. The implementation of COTS (Components Off The Shell) electronic components, military industrial grade, ensured a considerable saving in terms of costs with minimal impact on the final performance of the system. In order to reach the objective: the mission success (operative spacecraft for at least six months), it has been performed an FMEA analysis at system and subsystem level and a full test campaign useful to define and develop the hierarchical and distributed FDIR strategy here exposed.
