Dual Airborne Laser Scanner

Dual Airborne Laser Scanner (ALS) Inertial Navigator

Terrain data known:

• Perform precise terrain –referenced 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 “map”, use the other ALS and an inertial system to “navigate.”
• Drift reduction
