Ground-Based System Guides UAVs to Avoid Collisions

The Federal Aviation Administration (FAA) averages more than 100 reports a month of interactions between unmanned aircraft systems (UAS) and commercial or private planes. For UAS to fly in civil airspace, they must be able to see, avoid, and remain “well clear” of other aircraft. With no pilot onboard to spot approaching aircraft, another sense-and-avoid (SAA) technique is required.
