Sensor Fusion Engine
Multi-Sensor Fusion and State Estimation Engine
The Multi-Sensor Fusion and State Estimation Engine is an L1-CDH subsystem within the Lunar Ark that integrates telemetry from multiple instruments to produce unified system state awareness. Utilizing Kalman filtering, Bayesian inference, and sensor voting schemes such as 2-of-3 logic, it isolates faulty inputs and tracks measurement drift over time. Lunar operations over a 100-year mission require the architecture to adapt across multiple sensor replacement cycles. The engine performs online recalibration to correct radiation-induced drift, compensates for dust contamination degrading optical and thermal hardware, and differentiates lunar-normal environmental conditions from critical system anomalies.
Multi-sensor integration, state estimation, and situational awareness system
Purpose
Combine data from multiple sensors to create unified system state awareness
Context
Component of L1-CDH within the Lunar Ark system
Principles
- ▸Kalman filtering combines noisy sensor measurements into optimal state estimates
- ▸Sensor voting (2-of-3, weighted majority) detects and isolates faulty sensors
- ▸Bayesian inference quantifies confidence in system state given uncertain observations
- ▸Temporal correlation detects sensor drift and calibration degradation over time
Typical implementations
- ▸GPS/INS sensor fusion in navigation systems
- ▸Mars rover hazard avoidance stereo vision + LIDAR fusion
- ▸Nuclear power plant multi-sensor validation systems
- ▸ISS Caution and Warning System multi-sensor health monitoring
Lunar considerations
- ▸Sensor degradation from radiation requires online recalibration and drift compensation
- ▸100-year mission means sensors will be replaced multiple times - fusion must adapt
- ▸Environmental sensors must distinguish lunar-normal from anomalous conditions
- ▸Dust contamination can gradually degrade optical and thermal sensors
