BT’s international satellite communications centre dials up 30th anniversary
• Midlands centre helps to keep the world in touch
• Sixty-five giant satellite dishes dominate the 218-acre site
A giant BT satellite earth station in the Midlands, which has played a key role in worldwide broadcasts of some of the most dramatic events of the past three decades – such as the fall of the Berlin Wall, Princess Diana’s funeral and even the recent Beijing Olympics – is celebrating its 30th anniversary.
Madley Satellite Communications Centre, in Herefordshire, was constructed to meet the growing demand from people and businesses for more international communications services.
Today it handles thousands of telephone calls, data, internet and television links, faxes, specially tailored business services and a range of other communications every day to almost every country in the world.
The 218-acre site houses 65 aerial dishes. It is dominated by three dishes, each measuring 32-metres in diameter and weighing 290 tonnes. The largest aerials are made from metal and the latest, smaller ones have plastic moulds with metal supports.
The inaugural signal was transmitted from Madley’s Aerial 1 in the autumn of 1978, initially enabling more than 2,000 simultaneous calls to 34 countries in the Middle East and Africa in less than a second, via the Intelsat satellite, which was in orbit more than 22,000 miles over the Indian Ocean.
Identical second and third aerial dishes followed in 1980 and 1981 as the site developed and the demand for even more international services grew.
Since then the number of services have continued to expand, enabling even more people and businesses to stay in touch around the world, and towatch global events as they unfold on 24-hour television news outlets.
From the fall of the Berlin Wall and Live Aid concerts, to the funeral of Diana, Princess of Wales and the Asian Tsunami, and more recently the Beijing Olympics, specialists from Madley have played their part in creating and restoring communications around the world.
The use of satellite communications from Madley has enabled families, friends, businesses and journalists to stay in touch with and communicate more easily and safely from remote locations around the world, war zones and developing countries.
Madley’s hard rock base and relatively sheltered location, nestled in a bowl flanked by the Malvern Hills to the east and the Black Mountains of Wales to the west, prone to little radio interference and with relatively good transport links, made the former farm the ideal choice.
Before that, it gained notoriety as the former Royal Air Force base, from where Rudolf Hess was flown to attend the Nuremberg Trials in 1945.Madley Satellite Communications Centre took around two years to design and plan, with a specialist team flying in from Japan to help with the construction of the first dish.
In contrast, developments in technology have enabled more recent services to be provided by much smaller dishes, which can be built by BT engineers on site within hours.
Madley was originally built to provide expansion for BT’s inaugural satellite earth station at Goonhilly in Cornwall.
More than 100 staff are currently based at Madley, working in a variety of areas. As well as staff responsible for the running of the 24-hour communications centre, there are engineers, rigging teams, computer software specialists, draughtsmen and project managers.
Madley is also the base for BT’s Emergency Response Team, who can be called upon at any time to provide expert support to Aid Organisations,the Armed Forces and overseas service providers, principally in helping to restore communications in the wake of a range of natural and other worldwide disasters, such as the Tsunami.
The site also boasts the award-winning Madley Environmental Study Centre. Opened in 1994 and set in 15 acres, the educational conservation area – which became a registered charity in 2001 - welcomes up to 3,000 children a year.
A series of events are planned to celebrate 30 years of communications from Madley in the build-up to the anniversary of the first transmissions on November 19 and 20.
Nick Wood, station manager, said: “This anniversary is about looking to the future as well as celebrating with pride the communications achievements of the last 30 years.
“International communications have never been more important and we see a bright future for Madley playing a vital role in their development as one of the world’s great satellite earth stations.”
Staff past and present will be gathering for a series of commemorative events, with a special visit by Ian Livingston, BT’s Chief Executive, also planned, and local children, who will cut a special satellite aerial-shaped 30th birthday cake.
It will be particularly poignant for seven current employees who were working at Madley when the first signal was transmitted.
One of them, Alan Hyde, aged 46, an engineer, joined BT – formerly the Post Office Telecommunications – straight from school as an apprentice, and remembers the events well.
He said: “One minute I was at school, within weeks I was in amongst this amazing hive of activity, sharing a moment of communications history. It was extremely exciting, but a bit nerve-racking too because the technology was so new and different. There were lots of conversations with our counterparts in different countries, but everything went to plan.
“The development in communications since then has been amazing, and especially the pace of change. It will be interesting to see what the next 30 years brings.”

About the Technology
Each of Madley’s 65 satellite aerials works the same, regardless of their size. A signal is carried to an aerial, where it is amplified and the frequency converted to allow it to propagate into space. The signal is received by the satellite, which carries out signal processing and amplification (effectively acting as a technically advanced mirror) before retransmitting, down to the receiving aerial and out to the awaiting recipient of the telephone call or data transmission.
As well as overseeing communications and television links from satellites, Madley’s is also BT’s international gateway for all telephone calls and communications from national telephone exchanges around the UK when people phone or communicate abroad.
When someone makes an international call it will typically go through their local telephone exchange, onto the national ‘trunk’ network and into Madley’s Transmission Centre. Here all calls and other communications – such as data, mobile, text and faxes - are ‘compressed’ through International Switching Centres and into Madley’s International Telephone Exchange. It will then automatically select the most appropriate route needed to reach the final destination – via an international satellite or subsea fibre communications cable, with Madley providing access points for both.
