The ADS-B system is used as a supplementary data source for commonly used secondary radars or multilateration systems. Its function is based on airborne equipment which uses GPS for the determination of its own position, and subsequently automatically transmits position coordinates and other data to the control centre.


Main characteristics:

  • Invaluable aid for aircraft navigation in wide areas without radar coverage (vast non-settled areas, seas and oceans)
  • Provides backing up radar data in case of failure or planned maintenance of the radar equipment
  • Broadcasting the messages that include GPS based position of the aircraft
