Vigilant Aerospace Systems congratulates NASA and Lockheed Martin on the new low-boom supersonic aircraft, the X-59 Quiet Supersonic Technology (QueSSt), being selected by Popular Science Magazine as one of “The most impressive aerospace innovations of 2019.” Vigilant Aerospace provides FlightHorizonX to NASA’s supersonic research programs, allowing NASA researchers to track and log their supersonic flights. The FlightHorizonX software is a version of FlightHorizon specially modified to track NASA’s new, experimental supersonic transponders. These NASA supersonic research programs have included NASA’s SonicBAT (Sonic Booms in Atmospheric Turbulence) program, the QSF18 (Quiet Supersonic Flights) program, and the CST (Commercial Supersonic Technology) program. All have used FlightHorizonX for airspace situation awareness, traffic alerting and airspace logging. From the article:
“It’s been nearly a half-century since the FAA banned supersonic civilian flights over land because of the telltale booms they produce. NASA and Lockheed Martin hope to reverse that with their X-59 QueSST aircraft, currently under construction in California. The 97-foot-long experimental plane will fly faster than sound, but its designers have engineered it to do so as quietly as possible. Typical supersonic aircraft create a sonic boom when shock waves from the nose and tail merge; because of the X-59’s distinctive shape, those two ripples never do that, so the resulting sound is more like far-away thunder or a dull thump. If the initial flight, scheduled for 2021, goes well, the jet could help pave the way for airplanes that cut flight times in half.”
Vigilant Aerospace is looking forward to the further development of NASA supersonic aircraft and continuing to support these initiatives.

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.
