A collision and conflict avoidance system for an autonomous unmanned air vehicle (UAV) is provided. The system uses available on-board sensors to generate an image of the airspace surrounding the UAV. The sensor data is analyzed for imminent conflicts (collisions, TCAS violations, airspace violations), and, if a problem is detected, a search for possible avoidance routes is started. The avoidance routes as far as possible comply with statutory air traffic regulations. Depending on the available time, a short-term reactive algorithm using direct flight control system commands, or a medium-term path planning algorithm using a flight plan optimized under aeronautical and economical boundary conditions, may be used. In either case, the UAV may be returned to the original route. The system is particularly suited to allow the use of autonomous UAVs in both civil and military airspace. |
