How does satellite TV work? To understand this, you should know that satellite television works in the same way that a regular TV works. Radio signals are constantly transmitting programming that is received from a satellite that orbits our earth.
The satellites are orbited at approximately 22,000 miles above the earth, which is at about the same speed as the earth itself. This is called geosynchronous orbit and it means that the orbits of the satellites match the rate at which the rate at which the earth rotates. To a person on earth, it would appear as though the satellites aren't even moving. This 22,000 mile distance also allows the satellites to remain stationary over certain areas, which in turn is the reason that your smaller satellite dish does not have to move at all.
Each satellite in the sky receives signals transmitted from a satellite provider and then re-transmits them to earth over a wide geographical area.
No matter which satellite provider you choose, they all have their own private satellites. Each and every satellite provider has broadcasting facilities and this is where they gather all of their programming from content providers. Content providers are companies like NBC, HBO, CNN, etc. The satellite providers check signals for quality, encrypt them for security and then transmit these signals back up to the satellites. The information is then in a way deflected back to your dish. Your satellite dish then gathers this information and sends all the signals back to your satellite receiver. Your receiver then processes these digital signals and converts them into digital and audio output for your television.
Satellite TV enables the viewer to receive access to hundreds of channels. With satellite television, you are able to choose the channels you would like to have programmed into your system; you can also remove certain channels if you choose not to have them. Satellite TV is a great way to have clear picture, great audio and a varied choice of programming.
