What is ADS-B?
A clear introduction to ADS-B, the aircraft broadcast technology behind much of modern live flight tracking.
ADS-B stands for Automatic Dependent Surveillance–Broadcast. Aircraft equipped with compatible avionics broadcast identification, position and movement information. Ground receivers can capture those broadcasts and pass the data into tracking networks.
Why it matters on Sanum.store Flight Tracker
Live aviation data is easier to understand when each field has context. Sanum.store Flight Tracker combines raw aircraft positions with airport hubs, aircraft tracking and reference pages so visitors can move from a map marker to a clearer explanation of what they are seeing.
What can affect the value you see?
Aircraft equipment, receiver coverage, network timing and the upstream source can all affect what is displayed. Some fields can be missing or update at different intervals, and nearby terrain or sparse receiver coverage can reduce visibility.
