12/02/02 -- NATO Lectures Spotlight Uninhabited Air Vehicles
Nearly 100 researchers from around the world gathered for the NATO (North Atlantic Treaty Organization) lecture series. Sponsored by NASA’s Computing, Information, and Communication Technologies Program. The event was a unique opportunity for researchers to discuss with peers their current work in the area of uninhabited air vehicles (UAVs). UAVs are remotely piloted or self-piloted aircraft that can carry payloads such as cameras, sensors, and communications equipment.
