Royal Signals and Radar Establishment

[2] There were several out-stations in Worcestershire, including the ex-RAF airfields at Defford and Pershore and the satellite tracking station at Sheriffs Lench.

Some of the most important technologies developed from work at RSRE are radar, satellite communications, thermography, liquid crystal displays, speech synthesis and the Touchscreen.

The SRDE establishment moved to a RSRE facility at RAF Defford near Malvern in 1980, which had the benefit of flat terrain for good satellite dish positioning and the nearby Bredon Hill for satellite simulators.

RSRE was an early researcher of TCP/IP in Europe, along with Peter Kirstein's group at University College London and NDRE in Norway.

[6] The first email sent by a head of state was sent from the RSRE over the ARPANET by Queen Elizabeth II on 26 March 1976.
