Vigilant Aerospace Systems has participated as a co-author on a research paper from Oklahoma State University’s Unmanned Systems Research Institute (USRI) titled “Testing and Evaluation of UTM Systems in a BVLOS Environment.” The paper has been accepted for publication by the American Institute of Aeronautics and Astronautics (AIAA) and will be presented at the upcoming 2020 AIAA AVIATION Forum on June 17, 2020, which is an online event this year. The new research paper focuses on the use of ground-based radar and other sensors in the development of an effective detect-and-avoid and airspace management system to support the safe integration of unmanned aircraft into the US national airspace. The paper places particular emphasis on the development of effective unmanned traffic management (UTM) systems for beyond visual line-of-sight (BVLOS) flight of unmanned aircraft. The paper was written based on a research and development project with Oklahoma State University (OSU) funded by the Oklahoma Center for the Advancement of Science and Technology (OCAST). The paper was co-authored by Taylor Mitchell, Research Engineer; Marc Hartman, UAS Operations Coordinator; Dane Johnson, Research Engineer; Rakshit Allamraji, Reseach Engineer; Jamey D. Jacob, Professor and Institute Director, all from the Unmanned Systems Research Institute at Oklahoma State University; and Kraettli L. Epperson, CEO, Vigilant Aerospace Systems of Oklahoma City. Paper Abstract: Unmanned Traffic Management (UTM) systems of the future will require networks of systems both on the ground and onboard the Unmanned Aircraft System (UAS) to ensure safe aircraft separation and routing. To that goal, Oklahoma State University has partnered with Vigilant Aerospace Systems to operate a flight corridor to test these systems and work towards beyond visual line-of-sight (BVLOS) operations which can serve as a foundation for future UTM networks. Flights will be conducted between two airfields 13 miles apart in a rural airspace established under FAA Certificate of Authorizations (COAs) and Part 107 exemptions. Vigilant’s FlightHorizon software is to be utilized to provide aircraft traffic situational awareness and deconfliction routing using inputs from ADS-B, UAS telemetry, and radar systems installed at the airfields. Operations have already been tested using mobile observers for long-range flights to test the aircraft platforms, communications, and management software. This will soon transition to BVLOS testing utilizing the aforementioned technologies to satisfy FAA requirements for sense-and-avoid and then determine which of these technologies could help provide a minimum viable system for Unmanned Traffic Management.

About the AIAA AVIATON Forum

The AIAA AVIATION Forum was started in 2010 to bring the aviation industry together to address challenges and future direction of the industry with the objective of developing the premier forum for presentation of both recent progress on aircraft design, air traffic management and operations, and aviation technologies as well as policy, planning, and market issues affecting the future direction of the global aviation industry. The annual forum event provides a venue for interaction between researchers, system developers, product support personnel, managers, and business developers from throughout industry, government, and academia.

About AIAA

The American Institute of Aeronautics and Astronautics (AIAA) is the largest aerospace professional society in the world, serving a diverse range of more than 35,000 individual members from 80 countries, and 100 corporate members. AIAA was created in 1963 by the merger of the two great aerospace societies of the day, the American Rocket Society (founded in 1930 as the American Interplanetary Society), and the Institute of the Aerospace Sciences (established in 1933 as the Institute of the Aeronautical Sciences). The AIAA credo is “In Search of the Next Impossible Thing.” For more information, visit   Featured image credit: OSU/Jamey Jacob

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.
