Aeronautical communications, navigation, and surveillance systems are the backbone of air traffic management. These include surveillance (e.g. radar and multilateration), radio communications, and other key navigational and support equipment. Our technicians and engineers plan, develop, maintain, upgrade and restore these equipment on a continuous basis.
Assuring flawless communication between pilots and traffic control is key to air safety. Skyguide maintains a complete infrastructure. All communication systems are secured by often several fallback systems.
Radio navigational equipment provides signpost in the sky, enabling pilots who fly by instrument to stay on course in any weather.The three most important ground-based navigational aids are VOR, DME and ILS:
Satellite-based procedures are growing in importance and skyguide is developing, in collaboration with other partners, new satellite-based navigation procedures. Such procedures have already been successfully implemented, for example at Zurich airport and in the approach to Inselspital in Bern.
Radar is a radio-electric locating procedure, with differences between primary and secondary radar. While primary now plays a minor role in civil air traffic control, except for landing, it is important in compiling the visual representation of the air traffic for military airspace monitoring and fighter control.
Secondary radar equipment supplies additional information from aircraft equipped with transponders (IFR) – flight number, altitude, and speed – which also appears on the screen of the air traffic controller. Skyguide has 2 primary and 6 secondary radar devices, located in Geneva, Zurich, La Dôle and Lägern.
