In March, Greg Walker, UAF’s Unmanned Aircraft Program Manager, led research in the Aleutians. Walker flies the UAVs in just about all conditions except freezing rain which would stick to delicate equipment. “We’ve regularly flown in showers, we’ve […]
Unmanned Aircraft: Arctic science & technology
Speeding over Arctic sea ice, small remote-controlled aircraft snag video footage and high-definition shots of endangered Steller Sea Lions in their natural habitat. Quiet and unobtrusive, the machines can serve as Special Op.s for researchers. Low-altitude remote sensing using Unmanned Aerial Vehicles (UAVs) has vast potential… and we’re only beginning to explore it. Gregory Walker, […]
