What does ADS-B stand for?

The term ADS-B stands for Automated Dependent Surveillance - Broadcast. This system is a key component of modern air traffic management, using GPS data to determine an aircraft's precise location and then broadcasting that information to air traffic control and other aircraft. The "Automated" aspect refers to the reliance on onboard systems to gather data without the need for pilot intervention, while "Dependent" indicates that the system depends on external data sources, such as GPS. The "Surveillance" part relates to the monitoring of aircraft positions, and "Broadcast" signifies that this information is transmitted automatically to anyone equipped to receive it. This enhances situational awareness for both pilots and air traffic controllers, leading to improved safety and efficiency in air traffic management.
