First operational 11 June 1962. Goonhilly 1 is possibly the most famous satellite dish in the world – built in 1961~1962 to receive the first trans-Atlantic pictures from Telstar 1. The antenna is still fully functional. Currently established as a C-Band commercial satellite communications antenna, GHY-1 is soon to receive a new cryostat receiver and there are advanced plans to connect into the Jodrell Bank e-MERLIN interferometer network.
