ADS-B (Automatic Dependent Surveillance-Broadcast)

ADS-B, or Automatic Dependent Surveillance-Broadcast, is a surveillance technology in which an aircraft determines its position via satellite navigation and periodically broadcasts it, enabling it to be tracked. The information can be received by air traffic control ground stations as a replacement for secondary radar. It can also be received by other aircraft to provide situational awareness and information for collision avoidance. ADS-B is an integral part of the modern airspace system and is used for efficient navigation and safety. It is automatic in that no pilot or external input is required. It is dependent in that it relies on the data from the aircraft's navigation system. ADS-B functionality is integral to modern transponders and is a key technology in modern air traffic management systems. It provides enhanced surveillance capabilities to both pilots and air traffic controllers, and is more accurate and reliable than traditional radar systems.
