AeroVironment


AeroVironment, Inc. is an American defense contractor headquartered in Simi Valley, California, that is primarily involved in unmanned aerial vehicles. Paul B. MacCready, Jr., a designer of human-powered aircraft, founded the company in 1971. The company is probably most well known for developing a series of lightweight human-powered and then solar-powered vehicles. AeroVironment is the Pentagon's top supplier of small drones — including the Raven, Wasp and Puma models.

Vehicles developed

Among the vehicles the company built are:
AeroVironment holds a five-year, $4.7 million IDIQ contract from the U.S. Air Force Research Laboratory for the development of advanced propulsion technologies for UAVs. The contract also provides for specific technological tasks such as integration of solar cells into aircraft wings, electric motor efficiency improvement technologies, and development of hydrogen storage systems for aircraft.
In 2013, AeroVironment participated in the DARPA TERN program, and received $2 million for Phase 1 and $19 million for Phase 2. The "Tactically Exploited Reconnaissance Node" program attempts to launch and recover a UAV from mid-size ships to provide long distance intelligence gathering. However, in September 2015 AeroVironment was not selected to move onto Phase 3 of the program.

HAPSMobile

is a subsidiary of SoftBank planning to operate HAPS networks, with AeroVironment as a minority owner.
HAPSMobile develops the Hawk30 solar-powered unmanned aircraft for stratospheric telecommunications, and has a strategic relationship with Loon LLC, a subsidiary of Google's parent Alphabet Inc.

Subsidiaries

AeroVironment owns Skytower, Inc., which was formed in 2000 to develop the technologies and government approvals to use high altitude UAVs as "atmospheric satellites", or high altitude communications relay platforms.
In July 2002 the NASA/AeroVironment UAV Pathfinder Plus carried commercial communications relay equipment developed by Skytower in a test of using the aircraft as a broadcast platform. Skytower, in partnership with NASA and the Japan Ministry of Telecommunications, tested the concept of an "atmospheric satellite" by successfully using the aircraft to transmit both an HDTV signal as well as an IMT-2000 wireless communications signal from, giving the aircraft the equivalence of a tall transmitter tower. Because of the aircraft's high lookdown angle, the transmission utilized only one watt of power, or 1/10,000 of the power required by a terrestrial tower to provide the same signal. According to Stuart Hindle, Vice President of Strategy & Business Development for SkyTower, "SkyTower platforms are basically geostationary satellites without the time delay." Further, Hindle said that such platforms flying in the stratosphere, as opposed to actual satellites, can achieve much higher levels of frequency use. "A single SkyTower platform can provide over 1,000 times the fixed broadband local access capacity of a geostationary satellite using the same frequency band, on a bytes per second per square mile basis."
