Marambio Base
Encyclopedia
Prior to the base's foundation a team led by Vice-Commodore Mario Luis Olezza built the 1200 m (3800 ft) long, 40 m (120 ft) wide landing track, the first one in the continent. Nowadays, the track, oriented 05/23, is equipped with VOR
VHF omnidirectional range
VOR, short for VHF omnidirectional radio range, is a type of radio navigation system for aircraft. A VOR ground station broadcasts a VHF radio composite signal including the station's identifier, voice , and navigation signal. The identifier is typically a two- or three-letter string in Morse code...
