What is the primary purpose of ADS-B technology?

The primary purpose of Automatic Dependent Surveillance–Broadcast (ADS-B) technology is to provide real-time position data to Air Traffic Control (ATC) and other aircraft. This system enhances situational awareness and safety in the airspace by allowing aircraft to broadcast their location, velocity, and other data to ground stations and nearby aircraft equipped with the same technology.

This real-time sharing of information helps ATC with more accurate tracking of aircraft, especially in areas where traditional radar coverage may be limited. Additionally, it aids pilots in avoiding potential collisions by providing them with awareness of nearby air traffic, significantly improving overall airspace management.

Other options, such as increasing radar coverage in remote areas, do not accurately describe ADS-B since it relies on satellite and ground-based infrastructure rather than traditional radar. Tracking aircraft movements solely on the ground is not the primary function of ADS-B, as it is predominantly used for airborne surveillance. Lastly, while ADS-B can have applications in various operations, including military ones, it is not exclusive to military use; its primary purpose is to enhance the safety and efficiency of civilian air traffic.
