Ground-based sense-and-avoid display system (SAVDS) for unmanned aerial vehicles

摘要

The present invention is a Sense-And-Avoid Display System (SAVDS) that integrates airborne target position data from a ground-based radar with unmanned aerial vehicle (UAV) position data from the UAV ground control station (GCS). The UAV GCS receives the UAV position data from a global positioning system (GPS) element in the flight management autopilot system in the UAV. Using a high-resolution display, the SAVDS shows the GPS position of the UAV in relation to other radar-detected airborne targets operating in the same airspace. With the SAVDS co-located adjacent to the GCS computer controlling the UAV, the SAVDS instructs the UAV operator to change the heading and/or elevation of the UAV until any potential midair aircraft conflict is abated. The radar-detected airborne target data and the UAV GPS data are integrated and displayed with georeferenced background base maps that provide a visual method for tracking the UAV and for performing collision avoidance.
