ADS-B stands for what?

• A. Automatic Dependent Surveillance - Broadcast
• B. Airborne Data Surveillance - Broadcast
• C. Automatic Directional Surveillance - Broadcast
• D. Attitude Display Surveillance - Broadcast

Answer: (A)

ADS-B stands for Automatic Dependent Surveillance - Broadcast. Automatic means the system operates without radar interrogation. Dependent means it relies on the aircraft’s own navigation data (like GPS) to determine its position and velocity. Surveillance refers to providing air traffic surveillance data, not by radar scanning. Broadcast means this information is transmitted from the aircraft to ground stations and to other aircraft. This setup allows precise, real-time tracking over areas with limited radar coverage and supports safer, more efficient airspace management.
