Abstract

A satellite’s on-board computer must guarantee integrity and recover degraded or damaged data over the entire duration of the spacecraft’s mission in an extreme, radiated environment. While redundancy and hardware-side voting can protect Magnetoresistive RAM well from device failure, more sophisticated software-side storage concepts are required if advanced operating systems are used. A combination of hardware and filesystem measures can thus drastically increase system dependability, even for missions with a very long duration. We present a novel POSIX-compatible filesystem implementation offering memory protection, checksumming and forward error correction.
