.: Satellite TV: How Does This Actually Work?
Category:Home / Technology / Cable and Satellite TV
Satellite TV is TV delivered by way of orbiting communications satellites located 37,000 km above the earth's surface. To start a Satellite TV we have to locate a transmitting antenna at an uplink facility. Uplink satellite dishes go towards the satellite on which its signals are transmitted to & are very large in diameter, say about 9-12 meters or 30-40 feet. This large diameter gives a perfect positioning & a clear signal reception at the satellite. The satellite signals are retransmitted to Earth through transponders with a different frequency.
Satellite TV is much similar to the broadcast TV. Satellite TV is a wireless system for delivering television programming directly to a viewer's house. But in broadcast TV the major problem is of range because due to Earth's curved surface the signal line of site is broken many times. The other problem which broadcast TV gives is that there is much interruption in signal or the picture is distorted in the viewing area. Satellite TV solves all these problems of the range, broadcast signals, etc.
As due to Earth's surface the problem comes in signal but as satellites are high in the sky, the coverage scope for the customers is much more. They transmit & receive radio signals through satellite dishes which are a sort of specialized antennas.
The first Satellite TV was relayed from Europe to the Telstar Satellite over North America in 1962.Canada's Anik I, launched in 1973, was the first domestic North American Satellite to carry television.
