Adequacy of the FDIR design is often assessed very late in the process (integration and test phase), sometimes even after the launch of the spacecraft (FDIR parameter tuning). France GSTP G617-241TAeh THALES ALENIA SPACE FRANCE 2020 - 2022 De-risk assessment: Model Based FDIR design Validated reliability-based models for End of Life operations Reliability of End of Life operations is becoming a driver requirement for the design of future satellites, with an absolute value of reliability starting to be specified by international and national regulations and guidelines. France TDE T708-613SY THALES ALENIA SPACE FRANCE 2020 - 2021 Validated reliability-based models for End of Life operations Redundancy Concepts for Minimum Mass and Acceptable Failure Protection. The current redundancy approach is often intended to maintain or re-establish full functionality and performance capability in case of failure of a primary system or equipment. This naturally leads to build and carry system resources that may never be used in case the primary system works reliably throughout its operational life. On the other hand, alternative concepts exist which implement simply the capability of maintaining certain acceptable level of performance (i.e. graceful or acceptable degradation) in case the primary system fails.
