During a keynote at the small unmanned systems business expo in San Francisco, California, on July 25th., Alta Devices’ CEO Christopher Norris explained that small unmanned aircraft Systems (UAS) are no longer constrained to short-range or limited flight times and are now able to fly as long as the sun is shining.
This is expected to have tremendous economic value for agricultural, public safety, wildfire mapping, search and rescue, law enforcement, industrial applications, and many others.
In the past, solar solutions for powering these vehicles were either too heavy or could not produce enough power for long-range flight, or both. However, a small UAS outfitted with Alta Devices’ mobile power technology can produce enough power, while adding practically no weight, to fly indefinitely under the sun.
Alta Devices manufactures the world’s thinnest, most flexible, and most efficient solar material. It can be used on anything that moves, can be carried, or worn, to generate substantial power from light. In the case of a typical small UAS with a 9-foot wingspan, Alta’s material can generate roughly 125W of power and weigh about 125g (about 4.5 ounces). In many cases, this is enough power to sustain flight and keep an on-board power source fully charged.
Norris said, “A broad range of civil unmanned systems will benefit from extended range and endurance. For example, when a UAS is used to map a wildfire, or on a human search and rescue mission, it is critical to have flight times that are as long as possible.”
For agricultural use, the ability to extend the range of a UAS and shorten the task of monitoring a large area by avoiding stops to recharge, has significant economic benefit to the farming community.
