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
Precision approach radar

Precision approach radar

The RP-6PA precision approach radar is equipped with the latest technologies. The radar provides comprehensive information necessary for precise control of all types of aircraft for landing – the information about accurate aircraft position, and current deviation from the required descent path in azimuth and elevation.


Main characteristics:

  • Fully solid state technology
  • Antenna system with electronic scanning
  • Doubled configuration architecture
  • Modern radar data display software
  • The system has been designed and developed using state-of-the-art technologies
  • Modular design enabling modifications according to specific customer wishes
