The progress of communication technology that has been so quick to bring the ease of communication for many people of the world. Now people have had a thousand ways to stay connected to each other and exchange data with each other. Various means of communication through the cable and wireless is now offered by companies communication service. Various types of satellites also have been developed to support this operational communications.
If in 1962 AT & T Telstar communications satellite orbit was the first, now after a few decades and has been developing at least four types of satellites that will enliven 'sky' communication in the world. Type sateli first satellite is used for broadcasting television broadcast.
While the satellite is the second type of satellite that is used for the purpose of the GPS (Global Positioning System), which until now has been a total of 24 satellites in the world with the principle of using the concept of triangulation.

Type of satellite is the third satellite that is designed to make mobile phone service needs and various kinds of services in a way to use satellite transmission instead of the microwave transmission between countries. Basic idea of satellite communication is to overcome the limitations of the earth station microwave. Satellite communications is functioning as a microwave relay station mengorbit around the earth.
Type of satellite is the next high-speed satellite network that berorbit low allows the user so that the earth processes exchange data more quickly. This satellite is very important to be developed, many people still remember that we have not yet affordable high-speed Internet service, cable TV and Internet technology, the development of various other satellites. With the development of satellite technology, this also will enable us to send and receive packet data and voice over the phone with the speed equivalent to the Internet Broadband
