Satellite networks are systems that use satellites orbiting the Earth to provide communication services. These networks enable data transmission for various applications, including television broadcasting, internet access, and global positioning systems (GPS). Satellites can cover large areas, making them essential for connecting remote or underserved regions. The structure of a satellite network typically includes a satellite in space, ground stations on Earth, and user terminals. The satellites receive signals from ground stations, relay them back to Earth, and connect users to the internet or other communication services. This technology plays a crucial role in global connectivity and information sharing.
