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 replacing traditional radar for air traffic control, providing highly accurate aircraft position and status information.
- Aircraft automatically transmit precise GPS data every second to ground stations and other aircraft, offering significantly more frequent and accurate updates than radar.
- This enhanced accuracy allows ATC to reduce aircraft separation and implement more efficient routing, while also providing real-time traffic and subscription-free weather information to equipped aircraft.
