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 data from a ground-based short-range tracking radar with positional data from a global positioning system (GPS) element in the flight management autopilot system in the unmanned aerial vehicle. Using a high-resolution display, the SAVDS shows the GPS location of the unmanned aerial vehicle in relation to other aircraft operating in the same airspace. With the SAVDS co-located on the same tabletop as the computer controlling the unmanned aerial vehicle, the SAVDS operator can instruct the unmanned aerial vehicle pilot to change the heading of the vehicle until any potential aircraft conflict is abated. Ground-based radar data and GPS data are integrated and displayed with georeferenced base maps that provide collision avoidance information, and provide a means for tracking the UAV relative to geographic waypoints.
