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
