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 more precise aircraft detection and management.
- It provides highly accurate, real-time aircraft position, speed, and identification data by transmitting updates every second, significantly improving upon radar's 5-12 second scan rate.
- This enhanced accuracy allows ATC to improve efficiency through reduced aircraft separation and optimized routing, while also enabling direct information sharing among aircraft and providing weather services.
