What does 'ADS-B' stand for?

The term 'ADS-B' stands for Automatic Dependent Surveillance–Broadcast. This system is a crucial technology used in aviation for surveillance and situational awareness. It allows aircraft to determine their position using satellite navigation and periodically broadcast it along with other information, such as velocity and altitude. This broadcast is sent to ground stations and other aircraft, contributing to improved safety and efficiency in air traffic management.

The key components of ADS-B include its dependence on onboard satellite navigation (such as GPS), which provides accurate position information, and the broadcasting of this information, which is vital for both air traffic controllers and nearby aircraft. The system enhances situational awareness, allowing for streamlined air traffic control and reducing the risk of mid-air collisions.

Understanding this technology is essential for avionics technicians, as it plays a significant role in modern aviation safety and air traffic management practices.
