 Owing to the recent developments in technology satellite communication developed to outclass terrestrial communication especially at TV broadcasting. The major advantage of satellite communication is that it is the only solution for communication regardless of geographical distance and field conditions; moreover it can be utilized at locations without any infrastructure.
Furthermore the satellite communication offers much more efficient and high speed communication over the existing systems with different multiple accessing methods. • 
VSAT (Very Small Aperture Terminal) is the common name for the satellite stations with small diameter (0,8– 2,4 m) antennas. VSAT system provides duplex communication between central ground station (hub station) and local stations separated far apart . VSAT systems support a lot of different services such as voice, data, internet, intranet, video conferencing etc. The principal usage of VSAT systems nowadays is watching the TV broadcasts through sattelites by individual users. The fact that satellite communication systems can be used at locations far from the city centers that can not benefit the existing communication infrastructure broaden the usage of these systems widely.
