Sensor Diagnostics
Online Sensor Health Assessment and Fault Detection
System monitoring sensor health and detecting sensor failures or degradation
Purpose
System monitoring sensor health and detecting sensor failures or degradation
Context
Child of L2-CDH-FUSE
Principles
- ▸Innovation sequence analysis (Kalman filter residuals) detects sensor anomalies
- ▸Cross-sensor consistency checking identifies readings that disagree with physics models
- ▸Trend analysis detects gradual sensor drift or calibration degradation
- ▸Sensor fault isolation determines which specific sensor has failed in a redundant group
Typical implementations
- ▸NASA ISHM sensor diagnostics framework
- ▸Industrial process sensor validation systems (HART protocol)
- ▸Aircraft air data sensor monitoring systems
Lunar considerations
- ▸Radiation damage causes gradual sensor parameter drift over years
- ▸Must distinguish sensor failure from actual system anomaly
- ▸Sensor replacement scheduling based on diagnosed degradation rate
