Satelitní komunikace, or satellite communication, refers to the use of artificial satellites to provide communication services. It encompasses a range of technologies and applications that involve the transmission of data, voice, and video signals through satellite links. These satellites are placed in orbit around the Earth and can facilitate long-distance communication across vast distances, including remote and underserved areas where traditional communication infrastructure may be lacking.
The main components of satellite communication systems include the satellite itself, ground stations (which communicate with the satellite), and user terminals (which receive and transmit signals). Satellite communication is widely used for various applications, including television broadcasting, internet services, global positioning systems (GPS), maritime and aviation communications, and military communications. The technology allows for high bandwidth and connectivity over large geographic areas, making it a vital component of modern communication infrastructure. Additionally, it can operate in various frequency bands, such as C-band, Ku-band, and Ka-band, each serving different types of communication needs and applications.
Úvod: Moderní vojenské síly se silně spoléhají na satelity jako multiplikátory síly a zpravodajské prostředky ve vesmíru. Během posledních několika desetiletí se vedení války posunulo směrem k vysoce technologicky řízeným operacím, což činí vesmírné schopnosti stěžejními pro strategické plánování nsin.us. Vojenské satelity – kdysi omezené na špionážní mise z období studené války – dnes tvoří…
