Radio Research Station (UK)

The Radio Research Station (1924 – 31 August 1979) at Ditton Park, Near Slough, Berkshire, England was the UK government research laboratory which pioneered the regular observation of the ionosphere by ionosondes. In continuous operation from 20 September 1932, it applied the ionosonde technology for the early developments which led to the British Chain Home radar system, operational during World War II.
