What Is ADS-B and How Does It Track Flights?
ADS-B is one of the key technologies that helps aircraft share where they are while they fly.

What ADS-B means
ADS-B stands for Automatic Dependent Surveillance-Broadcast. In plain English, it is a system that allows an aircraft to broadcast information about itself.
That information can include the aircraft's position, altitude, speed, and identity. Receivers on the ground, on other aircraft, or in wider tracking networks can pick up those broadcasts.
Why it matters for flight tracking
ADS-B is one of the reasons modern flight tracking can be so detailed. Instead of estimating where an aircraft might be, systems can use broadcast position reports to plot its movement.
When enough points are captured, the route becomes visible as a line across a map.
Why coverage is not equal everywhere
ADS-B reception depends on receivers. Areas with many receivers can produce more complete tracking, while remote or oceanic areas may have fewer captured points.
This does not mean the aircraft was not broadcasting or that the flight did not happen. It simply means the available public track can vary.
Why it is useful for Stories Mapped
ADS-B and related aircraft position data help make flight path prints feel authentic. The artwork is based on a route with a real data story behind it.
That is what separates a custom flight path print from a decorative line drawn between two cities.
