Madley Communications Centre is British Telecom's earth satellite tracking station, between Madley and Kingstone, Herefordshire, England. It claims to be the largest earth station in the world.
It lies on Colstone Common at grid reference SO424374. The site dates from 1975 and is in active use for international telephone, fax and television transmission and reception. The station is in the civil parish of Kingstone, although most of the former airfield is in Madley, to the west of the site. A Roman road passes close to the north of the site.
Geology of the area
The site is in a sheltered rock bowl between the Malvern Hills and the Black Mountains. This allowed the ground to take the weight of the large receiving dishes, but the most important fact was the lack of background electronic noise. What nearby electronic noise there was compared to the strength of heat felt on the Moon from an electric fireplace on Earth.
There are sixty five dishes, with three main dishes each having a diameter of 32 metres and weighing 290 tonnes. Madley 1, the first of the dishes, tracks a satellite about 25,000 miles (40,000 km) away, positioned over the Equator in geostationary orbit.
Other use of grounds
The grounds are leased as an educational nature reserve, Madley Environmental Study Centre.
