FDIR Handling in Eu:CROPIS

Fault detection, isolation, and recovery (FDIR) mechanisms in on-board software are essential to guarantee the survival of the satellite in case of a hardware malfunction. E.g., outage of essential attitude control system (ACS) actuators or sensors can lead to mission loss. The on-board software has to handle such situation autonomously by switching to cold redundant devices or by isolation of information from hot redundant devices. The FDIR implementation for the ACS of the spin stabilized small satellite Eu:CROPIS (Euglena Combined Regenerative Organic food Production In Space) is shown in this paper
