Ever wonder how the television signal makes it to your home? All Satellite TV Companies deliver service from high-powered satellites located thousands of miles away in outer space. Satellite service is a highly sophisticated technology that consists of many components including: an uplink station, a high-powered satellite in outer space, along with a small antenna and receiving unit for one’s home or business. Whether you choose DIRECTV, DISH or another provider you’ll have a good understanding of how their service makes it into your home.
Here are some details on the pieces that make this all possible.
Broadcasters produce content and then set up agreements with providers to carry their programs. Once the broadcasters have produced the content it’s sent to the satellite provider which is then encrypted into a digital format and transferred to the uplink station for transmission located somewhere on the earth. In the United States, most of the satellites are operated in the southern hemisphere.
The Uplink Station
In means of communication this term can be used to describe the transmission of radio signals from earth to the high-powered satellite in outer space. Stations are set up with small to extremely large dishes ranging from a couple feet up to 40 feet in diameter. Larger satellite dishes often produce the ability to send more information at a faster rate and are known to be much more reliable than smaller dishes. Each station transmits data to a specific satellite in the sky within a specific frequency range.
The uplink station encrypts the data then sends it up to the high-powered satellite up in outer space. The data travels approximately 22000 miles into space. The satellite rotates within the geosynchronous orbit at the same rate as the earth. If the satellite didn’t rotate at the same speed as the earth this technology wouldn’t be possible.
Small Dish Antenna and Satellite Receiver
Today’s satellite dishes are very economical typically ranging from one to three feet (1 meter). Remember, you can always get a larger dish that will increase your signal and leave you less susceptible to outages. The satellite dish is set up outside then a cable is ran from the satellite dish into your home and into the satellite receiver. The satellite cable is not connected to a network and typically you don’t share the system with others so there is little room for error if there’s a problem.
In conclusion, the end user will receive channels based upon their subscription to the service. Channel availability is based upon the satellite provider. Satellite TV can be set up regardless of location along as there’s a clear view of the southern sky.
