How does a satellite work? How are live pictures and sounds transmitted across the world? How long before we will all be able to see the person we are talking to on the phone? Communications have come a long way since the telephone was invented in 1876! "Satellites and Communications" explains in simple terms the different kinds of communications we use today, from video phones, interactive television and the Internet to satellite links that can do anything from transferring telephone calls to telling ships and travellers their exact position anywhere on Earth.
