NASA Patent Licensed by Vigilant Aerospace Systems

The technologies were invented by Flight Systems Engineer Dr. Ricardo Arteaga working at NASA’s Armstrong Flight Research Center. The patent is the culmination of several years of work developing flight safety systems for drones and especially a focus on allowing drones to integrate with air traffic control, to enter the national airspace and to obtain authorization for beyond line-of-sight flight. The patent and associated licensed technologies have been used by Vigilant Aerospace as the basis for our new FlightHorizon UAS™ and FlightHorizon GA™ products, which were recently announced. Congratulations to Dr. Arteaga and the whole team at NASA Armstrong on the new patent and a bright future for safe unmanned flight in the national airspace! Want to know more about how FlightHorizon helps make drones safer?

About Vigilant Aerospace Systems

Vigilant Aerospace is the leading developer of detect-and-avoid and airspace management software for uncrewed aircraft systems (UAS or drones). The company’s product, FlightHorizon, is based on two NASA patents and uses data from multiple sources to display a real-time picture of the air traffic around a UAS and to provide automatic avoidance maneuvers to prevent collisions. The software is designed to meet industry technical standards, to provide automatic safety and to allow UAS to safely fly beyond the sight of the pilot. The software has won multiple industry awards and the company has had contracts and users at NASA, the FAA, the U.S. Department of Defense and with a variety of drone development programs.
