Why ADS-B?
Airlines and air navigation service providers benefit from improved low cost surveillance leading to safety enhancement, reduced workload for both pilots and controllers and more efficient operations.
Enablers for ADS-B
ADS-B used in air-to-ground applications provides support in all phases of flight and ground operations:
DESCRIPTION
The ADS-B ground station system provides the means of identification of other civilian aircrafts which are equipped with a Mode S compatible transponder. The system confirms to the relevant requirements of ICAO Annex 10, Vol. IV and STANAG 4193, Part 1, Edition 2. Thus it is compatible with all other IFF and SSR systems meeting those requirements. The major equipment items are in service with our army, navy, air force and civil aviation and qualified to meet ground station and warship environment, while all other component units are designed to meet these requirements. All that is necessary is the insertion of the appropriate computers into the secure housing supplied. All cabling and necessary controls form part of the offered system. The system is also supplied with Mode S facilities. However, to make full use of these facilities will require Data Handling capabilities external to the offered IFF/SSR system in order to initiate/ receive the necessary digital communication messages.

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.
