Satellitbølger

Satellitbølger refer to the radio waves used for communication with and between satellites. These waves are essential for transmitting data, signals, and commands to and from artificial satellites orbiting the Earth. Satellites utilize a range of frequencies for different purposes, including telemetry, tracking, command (TT&C), navigation, broadcasting, and scientific data collection.

The transmission of satellitbølger is governed by international regulations to avoid interference between different satellite systems and terrestrial services. These frequencies are allocated by organizations like the International Telecommunication Union (ITU). Common frequency bands used by satellites include L-band, S-band, C-band, Ku-band, and Ka-band, each with its own characteristics regarding bandwidth, atmospheric penetration, and antenna size requirements.

Satellitbølger travel through the Earth's atmosphere and space. Factors like atmospheric conditions, such as rain or clouds, can affect the signal strength and quality, particularly at higher frequencies. Satellite dishes on Earth are designed to accurately receive and transmit these waves to and from the satellites. The technology behind satellitbølger is crucial for a wide array of modern services, including global positioning systems (GPS), satellite television, internet access, weather monitoring, and space exploration.
