satelliittitelevision

Satelliittitelevisio, often shortened to sat-tv, is a method of broadcasting television programs by relaying them from an orbiting satellite to terrestrial receivers. This technology allows for the transmission of a wide range of channels over vast geographical areas, overcoming limitations of terrestrial broadcasting which relies on ground-based transmitters. Satelliittitelevisio typically requires a satellite dish antenna, which is installed at the viewer's location and precisely aligned to receive signals from the designated satellite. A set-top box, also known as a receiver, is connected to the dish and decodes the incoming signal, converting it into a format viewable on a television set.

The satellite itself is positioned in a geostationary orbit, meaning it remains in a fixed position relative to the Earth's surface. This allows the satellite dish to maintain a constant connection without needing to track the satellite's movement. Satelliittitelevisio offers advantages such as access to channels not available through local networks, often including international programming. It is particularly useful in remote or rural areas where traditional cable or terrestrial infrastructure may be absent or unreliable. The quality of the signal can be affected by weather conditions, with heavy rain or snow potentially causing temporary signal degradation.
