Sunglider reaches stratospheric altitude in 20-hour test flight
Successfully demonstrates broadband mobile communication on consumer smartphones, linking teams in Tokyo, New Mexico and Silicon Valley
AeroVironment, Inc. (NASDAQ: AVAV), a global leader in unmanned aircraft systems (UAS), today announced the Sunglider™ solar-powered high-altitude pseudo-satellite (HAPS) achieved key test milestones, including reaching an altitude of more than 60,000 feet above sea level and successfully demonstrating mobile broadband communication. Sunglider’s development and testing is funded by HAPSMobile Inc., a joint venture majority-owned by SoftBank Corp. (TOKYO: 9434) and minority-owned by AeroVironment.

During the test flight, which began at 5:16 a.m. MDT on September 21 and concluded at 1:32 a.m. MDT on September 22, the AeroVironment team piloted Sunglider to a stratospheric altitude of 62,500 feet above Spaceport America in New Mexico. Sunglider successfully achieved major test objectives relating to propulsion, power systems, flight control, navigation and datalink integrity, as well as structural performance during the most turbulent phases of the flight as it entered and exited the jet stream.
The broadband communication demonstration successfully linked teams in Tokyo, Spaceport America and Silicon Valley using an LTE payload jointly developed by Alphabet’s Loon LLC and HAPSMobile. Employing standard LTE smartphones, a team at Spaceport America conducted multiple video calls via the Sunglider’s payload while the aircraft circled for more than five hours in the stratosphere.
"In less than three years AeroVironment and HAPSMobile have made incredible progress, developing two Sunglider solar HAPS unmanned aircraft and performing five consecutive flight demonstrations, culminating in this latest significant milestone," said Wahid Nawabi, president and chief executive officer of AeroVironment. "Reaching stratospheric altitude, maintaining continuous flight for more than 20 hours, achieving key test objectives and demonstrating seamless broadband communication illustrate the tremendous potential HAPS technology offers to expand connectivity globally. We look forward to maintaining our momentum toward aircraft certification and commercialization, working in close partnership with HAPSMobile as we establish a disruptive capability that offers tremendous value creation potential."
The Sunglider, a solar-powered HAPS, has a wingspan of 262 feet and is propelled by 10 electric motors powered by solar panels covering the surface of the wing and rechargeable battery packs, resulting in zero emissions. Flying at an altitude of approximately 65,000 feet above sea level and above the clouds, the Sunglider can carry payloads weighing as much as 150 pounds and is designed for continuous, extended missions of months without landing.
