Vigilant Aerospace has completed successful beyond line-of-sight flight testing of its new FlightHorizon detect-and-avoid collision avoidance system for unmanned aircraft at NASA Armstrong Flight Research Center at Edwards AFB in California.
The tests demonstrated the system’s ability to provide beyond line-of-sight flight safety for both small and mid-sized unmanned aircraft to help comply with FAA regulations and integrate drones into the national airspace.
The flights tested the system’s detect-and-avoid (DAA) algorithms, hardware integration and user interface performance and included nearly 100 scripted encounters between unmanned aircraft under realistic flight conditions. The system successfully detected and tracked intruder aircraft and provided traffic alerts and collision warnings on 100% of air traffic during the encounters.
Eighteen different scenarios were flown multiple times using two DJI Phantom 4 drones with one aircraft acting as the primary ‘own ship’ while the other acted as an intruder aircraft. The scenarios triggered the system’s traffic alerts, threat alerts and collision warnings, allowing the drone pilots to avoid collisions between the aircraft. The encounters included beyond line-of-sight flights that simulated real-world scenarios in which visual detection of approaching aircraft by ground-based unmanned pilots might not be possible due to distance, weather, altitude and speed.
The tests were observed by the FAA’s senior UAV regulator, by an FCC observer to monitor radio transmissions, and were the culmination of a multi-month program of development, safety planning and test preparation, concluding in December 2016.
Vigilant Aerospace has exclusively licensed the NASA patent and software which forms the basis for the company’s FlightHorizon product and was invented by Dr Ricardo Arteaga at NASA Armstrong.
A significant advantage of the FlightHorizon system is that it utilizes off-the-shelf hardware, uses the existing national air-traffic control system, and can be used on both smaller and larger UAVs.
