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:
- ADS-B is a GPS-based system designed to replace traditional radar for air traffic control, providing enhanced aircraft detection and management.
- It transmits highly accurate, real-time aircraft position and speed data automatically and frequently (at least once per second) to ground stations and other aircraft.
- This improved accuracy over radar allows Air Traffic Control to reduce aircraft separation and implement more efficient routing, while also enabling data sharing between aircraft and offering free weather information to UAT-equipped planes.
