The Lorenz beam was blind-landing radio navigation system developed by C. Lorenz AG in Berlin. The first system had been installed in 1932 at Berlin-Tempelhof Central Airport, followed by Dübendorf in Switzerland (1934) and others all over the world.[1] The Lorenz company referred to it simply as the Ultrakurzwellen-Landefunkfeuer, German for "ultra-short-wave landing radio beacon", or LFF. Prior to the World War II the Germans had deployed the landing aid system at many Luftwaffe airfields in and outside Germany and equipped most of their bombers with the radio equipment needed to use it. The RAF continued using the system as late as 1955, under the name Standard Beam Approach (SBA)
The long range version developed by the Germans during the war was used by many countries for civilian purposes after the war, mostly under its English name Consol. Transmitters were installed in the US, the UK and the USSR.
