The company exclusively licensed NASA’s Patent No. 9,405,005 in 2016, which formed the basis for the company’s award-winning FlightHorizon products.The newly licensed patent, Patent No. 10,302,759, depends on the innovations in the original patent but extends them to include the use of radar for detect-and-avoid and situational awareness on-board the unmanned aircraft system (UAS), fusion of radar with other data sources for detect-and-avoid and various other innovations.
“We are delighted to continue to collaborate with NASA at the frontiers of autonomous systems and unmanned aircraft technology. This new agreement positions the company to further develop our products to incorporate the latest technology from the world’s leading aerospace research organization,” said Vigilant Aerospace CEO, Kraettli L. Epperson.
“The addition of patent coverage for the use of radar in unmanned aircraft detect-and-avoid and situational awareness systems is a significant milestone for the company and for the industry. We look forward to bringing to market the most advanced American unmanned aircraft technology to safely integrate UAS into the national airspace and to enable the future of aviation,” said Epperson.

The new patent covers the use of radar to extract target data for detect-and-avoid purposes on an unmanned aircraft; fusing of radar target data with data from other sources to confirm targets; storage and processing of consolidated target data on-board the aircraft; the use of fused data on-board the aircraft for avoidance purposes; innovations around dynamically and automatically switching from ground-based to on-board sensors based on link availability; and the use of an on-board detect-and-avoid computer, among other innovations.
“Radar is a critical addition for safety because it allows detect-and-avoid and airspace management systems to see both aircraft with transponders – cooperative traffic – and aircraft without transponders – non-cooperative traffic,” said Epperson. “Safe flight of UAS beyond visual line-of-sight requires the ability to see and avoid all kinds of aircraft and this new patent allows us to incorporate that into our products.”
The original NASA patent licensed by the company (Patent No. 9,405,005) covered innovations related to detect-and-avoid for unmanned aircraft including inventions around user interface design for collision avoidance systems for unmanned aircraft and integration of transponders into unmanned aircraft, among several other innovations.
Interested parties should contact the company to discuss FlightHorizon, collaboration and partnerships.
The FlightHorizon System
Vigilant Aerospace Systems provides the FlightHorizon family of detect-and-avoid and airspace management products. The FlightHorizon system provides air traffic monitoring and avoidance advisories to help drones maintain required well-clear distances from other aircraft and allow safe drone flight beyond the visual line-of-sight (BVLOS) of the pilot.
The company’s primary product is currently being used in multiple NASA and FAA projects, is used by multiple FAA Integration Pilot Project (IPP) teams, and the company has co-authored multiple research papers on the system with NASA. The company has obtained a US State Department Commodity Jurisdiction (CJ) ruling to allow for export of the product outside the US without additional licensing, in most cases.

U.S. Patent No. 9,405,005 – “Automatic dependent surveillance broadcast (ADS-B) system for ownership and traffic situational awareness”- Google Patents [Link]
- U.S. Patent and Trademark Office (USPTO) [Link]
- Abstract:The present invention proposes an automatic dependent surveillance broadcast (ADS-B) architecture and process, in which priority aircraft and ADS-B IN traffic information are included in the transmission of data through the telemetry communications to a remote ground control station. The present invention further proposes methods for displaying general aviation traffic information in three and/or four dimension trajectories using an industry standard Earth browser for increased situation awareness and enhanced visual acquisition of traffic for conflict detection. The present invention enable the applications of enhanced visual acquisition of traffic, traffic alerts, and en-route and terminal surveillance used to augment pilot situational awareness through ADS-B IN display and information in three or four dimensions for self-separation awareness.
