When you make a telephone call, when you watch a television show, or when you use the Internet, all your actions are relayed through a communication satellite. In 1945, Arthur C. Clarke predicted in an issue Wireless World, that satellites capable of communicating would one day circle the Earth. In 1947, he became the father of modern communications through inspired discovery of the "Clarke Orbit" (today it is known as the geostationary or geosynchronous orbit) which allowed the development of the first communication satellites.
Today, communication satellites can be found not only in the original geostationary orbits but also in Medium Earth Orbits (MEO) and Low Earth Orbits (LEO) as well. Malaysia joined the rarefied ranks of countries with their own telecommunication satellites with the launch of MEASAT-1 in 1996.
