Inside the Test Flight of Facebook’s First Internet Drone
July 21st, 2016Via: The Verge:
In its first flight, Aquila exceeded engineers’ expectations for its energy efficiency. More test flights are planned, aimed at flying Aquila “faster, higher, and longer,” says Jay Parikh, Facebook’s vice president of engineering, in a blog post today. And then Aquila will have its next big test: flying with the “payload,” as Facebook calls the laser communication system that a team is building in Woodland Hills, CA. In July 2015, the team announced that its lasers could deliver data at tens of gigabytes per second, about 10 times faster than the previous standard. And the lasers are quite precise, able to target an area the size of a dime from 10 miles away. (The lasers connect with base stations on the ground to supply internet access.) Facebook says the system has performed well in independent tests.
When will a fleet of Aquila drones bring data to the world? Facebook won’t say. There are several technical challenges remaining in getting Aquila to reliably fly 90-day stretches. The team hasn’t yet implemented solar panels on the prototype — the test flight plane ran using batteries only. The team is still working out how to build batteries with a density high enough to sustain lengthy missions. Then there’s the cost — Facebook says Aquila needs to be much cheaper if the world is going to deploy a fleet of them. “We need to develop more efficient on-board power and communication systems; ensure the aircraft are resilient to structural damage to reduce maintenance costs and able to stay aloft for long periods of time to keep fleet numbers low; and minimize the amount of human supervision associated with their operation,” Cox wrote in a blog post today.
Aquila is also likely to face regulatory obstacles, which could rival the laws of physics in terms of the challenges they present.
