the longest flying solar powered drones to help. satellites are constantly on the move, so you have to figure out a way to capture the information from which one of them while they're passing over a specific place. >> how to make all those satellites interconnect with each other, to have an internet back lone flying through the air as the satellites are moving by you. so that works really well in low density environments. but the challenge with that is that the further you get away, the weaker the signal gets. >> reporter: solar powered unmanned aircraft can offer a solution. >> so we're looking at a new type of plane architecture that flies at roughly 20,000 meters. it has a points where it's above commercial airlines, even above the weather and can stay in the air for months at a time. these planes are solar powers and they sit there and they just
