Model-Based Fault Diagnosis

Model-Based Fault Detection + Isolation Engine

The Model-Based Fault Detection and Isolation Engine is an autonomous software component stored on radiation-hardened NOR flash that identifies infrastructure anomalies across lunar installations. Drawing 2 W of power, the zero-mass engine compares observed system telemetry against digital twin predictions, isolating faults through residual pattern matching within a 10-second detection latency. Autonomous diagnosis is essential for long-duration lunar missions, where multi-decade operational horizons and uncrewed periods preclude continuous human oversight. Built for a 100-year operational lifetime with a 500,000-hour mean time between failures, the engine ingests authenticated model updates to maintain baseline diagnostic reliability over extended deployments.
