1948: More Outstations are created after the formation of the Radio Research Organisation

In 1948, the Radio Research Station became the Radio Research Organisation, under the directorship of R.L. Smith-Rose. Although a number of outstations already existed, more were now formed.

• The Burghead ionosonde station (1941 - 1947) was replaced by one at Fraserburgh which was eventually moved to Inverness (1948-1963).
• The Port Stanley ionosonde (1945-) was taken over by the RRS from the Navy in 1947
• The Singapore ionosonde (1948 - 1971) made measurements of the equatorial regions
• In 1948, an Ionosonde in Port Lockroy (Grahamland) made the first ever ionospheric measurements in Antarctica
• There were many other sites, mostly near Slough that were used occasionally.
