Facebook tests full-scale solar-powered Internet drone

Facebook's Connectivity Lab announced that the company has for the first time test-flown a full-scale version of Aquila, the solar-powered high-altitude drone that Facebook hopes to use to deliver Internet connectivity to the remotest populated corners of the Earth. The test flight took place June 28. The low-altitude test flight was originally intended only as a 30-minute “functional check” flight. "It was so successful that we ended up flying Aquila for more than 90 minutes—three times longer than originally planned," wrote Jay Parikh, Facebook's vice president of infrastructure engineering.

The goal of Aquila is to provide what has been described as an "atmospheric satellite" capability—the drones will fly for up to three months at a time, orbiting over remote areas and providing connectivity for a circle as much as 60 miles in diameter, using a laser-based network "backbone" and radio signals for local bandwidth. Because of its lift-to-weight ratio, Aquila can fly as slowly as 25 miles per hour in level flight.
