Communications, Navigation, Surveillance and ATM systems

Set of activities related to determination of necessity, acquisition, installation and maintenance of communication systems (ground-ground and air-ground), ground air navigation systems (at the airports, aerodrome areas and en-route), surveillance systems (for the purposes of the air traffic control performed by the air traffic control units) and air traffic management (ATM) systems. The existence of modern and reliable communications, navigation, surveillance and ATM systems is one of the main prerequisites for provision of high level air traffic services at the airports and in the airspace.
