Avionics and onboard computing

Flight computers, data buses, and the radiation-driven choices that make them unusual.

Scope

• Radiation-hardened and radiation-tolerant processors
• Redundancy: cold, warm, hot and voting architectures
• Data buses: MIL-STD-1553, SpaceWire, CAN, SpaceFibre
• Flight software architecture and frameworks
• Memory scrubbing and error detection and correction
