Dual Airborne Laser Scanner
Dual Airborne Laser Scanner (ALS) Inertial Navigator
Terrain data known:
- Perform precise terrain āreferenced navigation using a single ALS, an inertial system, and the known terrain data
- Drift free operation: demonstrated with sub-meter level accuracies.
Terrain data known or sparse:
- Use one ALS to āmapā, use the other ALS and an inertial system to ānavigate.ā
- Drift reduction
