Vigilant Aerospace Systems, Inc is a software development company based in Oklahoma City, Oklahoma. The company specializes in multi-sensor airspace management and detect-and-avoid products and is the developer of the FlightHorizon software. The FlightHorizon detect-and-avoid system is designed to provide deconfliction, situational awareness and safety for any remote pilot of an uncrewed aircraft, including both military and civilian aircraft. The system is suitable for use by both defense and commercial customers for governmental and non-governmental purposes and flights, and has been used by NASA, the FAA and by federally designated UAS Test Sites for a variety of research and development projects. The FlightHorizon product is based on two licensed NASA patents and is designed to provide real-time airspace situational awareness to uncrewed aircraft pilots, to provide automatic detect-and-avoid functions and to allow UAS and AAM aircraft to “see-and-avoid” other aircraft, maintain separation from air traffic and avoid mid-air collisions.
