SLAM Localization Engine
Multi-Sensor Visual + LIDAR + IMU SLAM
The SLAM Localization Engine is an autonomous navigation software suite hosted on radiation-hardened NOR flash and a GPU accelerator, drawing 5 watts of power. It fuses visual telemetry, LIDAR geometry, high-rate inertial measurements, and absolute fixes from LunaNet or local beacons into a unified position estimate. Optical tracking is severely challenged by the Moon's low-texture, feature-sparse terrain; the engine mitigates this by integrating geometric LIDAR data and digital elevation model feature anchoring to constrain drift, maintaining 1-meter global consistency at an update rate of 10 hertz across operational surface deployments.
Simultaneous Localization and Mapping engine fusing visual, LIDAR, IMU, and absolute fix into unified pose estimate for autonomous navigation across the Ark site.
Purpose
Simultaneous Localization and Mapping engine fusing visual, LIDAR, IMU, and absolute fix into unified pose estimate for autonomous navigation across the Ark site.
Context
Child of L2-NAV-LOC within the Lunar Ark system
Principles
- ▸Visual SLAM with DEM-anchored features (arXiv 2603.17229)
- ▸LIDAR SLAM for geometric features
- ▸IMU pre-integration for high-rate motion
- ▸Absolute fix from DSN/LunaNet/beacon constrains drift
- ▸Loop closure for consistent global map
Typical implementations
- ▸Mars rover ORB-SLAM (heritage)
- ▸Visual SLAM with DEM Anchoring (arXiv 2603.17229)
- ▸Autonomous Lunar Rover Localization (PMC 11479029)
Lunar considerations
- ▸Lunar low-texture terrain favors LIDAR + learned features
- ▸Long-mission map evolves with operations
- ▸Authenticated DTN updates
