GEO Satellites: Revolutionizing Global Communication and Navigation
GEO satellites, or Geostationary Earth Orbit satellites, are a type of satellite that orbits the Earth at an altitude of approximately 36,000 kilometers, remaining stationary relative to a fixed point on the Earth’s surface. This unique characteristic allows GEO satellites to provide a wide range of services and applications, including global communication, navigation, weather forecasting, and Earth observation.
GEO satellites have been in use for several decades, with the first GEO satellite, Syncom 2, launched in 1963. Since then, the technology has advanced significantly, with modern GEO satellites offering higher bandwidth, greater capacity, and improved performance. Today, GEO satellites play a vital role in global communication, providing connectivity to remote and underserved areas, as well as supporting a wide range of industries, including telecommunications, broadcasting, and finance.
