Trending and Anomaly Detection

Trending + Anomaly Detection Across Equipment

The Trending and Anomaly Detection module is a prognostics and health management software unit stored on radiation-hardened NOR flash that continuously aggregates sensor data across 200 equipment subsystems at 1 Hz to detect parameter drift, outliers, and impending failures. Because lunar operations demand autonomous long-mission reliability across decades without direct terrestrial maintenance, the system employs statistical trending and isolation forest anomaly detection to evaluate cross-equipment correlations. Consuming 2 W with a 100-year operational lifetime and an MTBF of 500,000 hours, the architecture executes authenticated updates and generates confidence-weighted alerts.
