What is ADS-B?

ADS-B is a GNSS dependent surveillance system. The aircraft receives data from navigation satellites via a GNSS receiver, and then broadcasts information on its identification, position, altitude, speed, intention, and other relevant data up to twice a second. The data received by ground stations are then transmitted to the air traffic management (ATM) system for display to air traffic controllers who use it to maintain aircraft separation in controlled airspace.

ADS-B Ground Station

Provides the ground segment of ADS-B air traffic control surveillance system for en-route, terminal area and surface movement control. Using 1090 Mode S Extended Squitter data link, the system outputs decoded data as Asterix category 21 to an attached network.

Air Traffic Control

It displays ADS-B data fully integrated on the same screen as flight plan data, radar data & ADS-C data.

A-SMGCS

Fuses data from multiple sensors, including ADS-B receiver and Mode S Airport Ground Sensor (MAGS) signal. Includes automatic provision of alerts and warnings, as well as traffic routing capabilities.

Multilateration - A passive co-operative sensor system, with full ADS-B capability, for surveillance and identification of suitably equipped aircraft and vehicles.

Vehicle management - A multi-link transmitter for vehicle management providing position and identification information to the airport’s A-SMGCS through multiple signal outputs including Mode S.
