What is ADS-B and what benefits does it bring to ATC operations?

ADS-B is a surveillance technology where the aircraft determines its own precise position (usually via GNSS) and broadcasts that position, along with velocity and other data, to air traffic control ground systems and to other equipped aircraft. This self-reported, high-update-position data gives ATC a much more accurate and timely view of aircraft locations than traditional radar alone. Because the information is broadcast directly from the airplane, coverage improves in areas with limited radar reach and supports higher traffic density by enabling tighter, safer spacing and more efficient sequencing. In short, ADS-B provides better situational awareness for controllers, enhances surveillance accuracy, and can increase airspace capacity and safety.
