ADS-B Box
ADS-B Automatic Dependent Surveillance-Broadcast
In addition to receiving over 45 different government air traffic control and private datalink sources. ADS-B BOX operates a worldwide network of ADS-B and Mode S receivers that track ADS-B or Mode S equipped aircraft flying around the globe.
ADS-B equipped aircraft to emit their exact position, and Mode S aircraft can be tracked via multilateration (MLAT) when the signal is received by three or more receivers.
ADS-B Box owns and operates these receivers at hundreds of airports around the world in conjunction with airport operators.

How it works:
Aircraft know their location based on GPS or similar technology and their altitude based on a pressure altimeter. Aircraft with an ADS-B transponder broadcast their identification and this three-dimensional position (latitude, longitude, altitude) on 1090 MHz or 978 MHz, which can be received by radio within line of sight of aircraft (a maximum of 300 mil/ 480 km at cruise). Receivers around the world send this data over a real-time connection to ADS-B Box, which aggregates the data and provides flight tracking data and interfaces. Approximately 70% of airlines around the world and 10% of private jets currently have ADS-B, whereas nearly 100% have Mode-S.
