Within the Dutch airspace there is a network of navigation beacons that mark the airspace structure, including VHF Omnidirectional Range (VOR), Distance Measuring Equipment (DME) and Non-Directional Beacon (NDB) for the benefit of navigation and guidance of civil air traffic. Besides the beacons that mark the airspace structure, Instrument Landing Systems (ILS) combined with DME are used for accurate landings on almost all civil airports.
