Automatic dependent surveillance-broadcast is a GPS-based system meant to replace the traditional radar-based technology ATC has relied on for decades to detect and manage aircraft traffic.
How It Works: ADS-B
Key Takeaways:
- Automatic dependent surveillance-broadcast (ADS-B) is a GPS-based system designed to replace traditional radar for air traffic control, offering enhanced accuracy and efficiency.
- Aircraft transmit precise position and flight data to ground stations and other aircraft a minimum of once per second, providing a much more accurate traffic picture than older radar systems.
- This improved data allows air traffic control to reduce separation between aircraft and implement more efficient routing.
- ADS-B also enables real-time information sharing between equipped aircraft, and those with Universal Access Transceivers (UAT) can receive subscription-free weather.
