What is Satellite (What is Satellite TV?).

In summary, similar to a television broadcast satellite television broadcast a lot. A wireless system for delivering television programming directly to the home audience . Both television broadcast and satellite stations will also send items through radio signals.

Broadcast stations use a powerful antenna to transmit radio waves to the surrounding area . Viewers can get a signal with an antenna that is smaller than most. Limitations of television broadcast is frequency. Radio signals used for television broadcast antenna is shot out of a straight line. To receive these signals , you must be in the same direction as the line of sight (Line of sight) of the transmitter antenna . Smaller obstacles such as. Houses a small tree or not an issue. But the big obstacle will reflect these radio waves .If our world is really flat . You can receive a signal from a television broadcast several thousand kilometers from the station . But because our planet is spherical . Eventually interrupt the lines of the signal. Another problem with the TV broadcast signal is often distorted , making viewing even in areas normally. To get a perfectly clear signal like you find on cable TV . You will be close enough to the transmitter antenna without too many obstacles in the direction of the antenna, the transmitter with you.

Satellite television solves both these respects by sending broadcast signals from satellites orbiting the Earth . Because the satellite is high in the sky. So there are a lot of people who are in line of sight. Satellite TV systems transmit and receive radio signals using specialized antennas called satellite (Satellite dishes).

High up in the sky than a satellite TV antenna . Therefore, it is broader than the line of sight .

Satellite TV is all but spent in orbit. Geosynchronous orbit , which means that these satellites are in place in the sky relative to the Earth . Each satellite was launched into space at a speed of about 7,000 mph ( 11,000 kilometers per hour) to an altitude of about 22,200 miles ( 35,700 kilometers) above Earth at the speed and height of this size. Satellite rotates around the earth every 24 hours during the first round in the same time with the rotation of the first round or the fact that the satellite orbit with the Earth's rotation . So you just turn in the direction of the satellite dish only once. From then onwards it received satellite signals without additional customization . At least when everything is running as normal.
