The Standard Terminal Automation Replacement System (STARS) is a modern air traffic control system designed to enhance the efficiency and safety of terminal airspace operations. It replaces older systems with advanced technology that improves radar tracking, flight data processing, and communication between air traffic controllers and pilots. STARS is part of the broader initiative to modernize the United States' air traffic management infrastructure. By integrating with other systems, such as NextGen, it aims to streamline air traffic flow, reduce delays, and improve overall safety in busy airports across the country.
