Satelliidisignaali

Satelliidisignaali refers to the radio waves transmitted from a satellite in orbit around the Earth. These signals are used for a variety of purposes, including communication, broadcasting, navigation, and scientific research. Satellites receive signals from ground stations or other satellites, process them, and then retransmit them back to Earth. The frequency and power of these signals are carefully chosen to ensure effective transmission and reception, while also minimizing interference with other services.

The reception of a satelliidisignaali typically requires a specialized antenna, such as a satellite dish, which is designed to focus the weak incoming signals. This signal is then processed by a receiver, which converts it into a usable format. For example, in satellite television, the signal is demodulated and decoded to display channels on a television set. In satellite navigation systems like GPS, the signal contains precise timing and positional information that allows a receiver to calculate its location. The reliability of a satelliidisignaali can be affected by atmospheric conditions, obstructions, and the satellite's orbital position.
