Communication satellites cover vast geographical areas, frequently spanning continents or even the entire globe. They facilitate global connectivity and communication between different regions of the world by relaying signals between ground-based communication stations. Depending on their intended applications and coverage requirements, communication satellites can be placed in various orbits. Geostationary Earth Orbit (GEO) satellites are 35,786 kilometers above the Earth's equator and remain fixed about the Earth's rotation. This enables them to provide continuous coverage over a specific geographic area. Low Earth Orbit (LEO) satellites, on the other hand, orbit at altitudes ranging from a few hundred to a few thousand kilometers from the Earth.
LEO satellites have advantages such as lower latency and higher data transfer rates, but providing global coverage requires a larger number of satellites.
Transponders are built into communication satellites to receive signals from one location and retransmit them to another. Transponders receive incoming signals, amplify them, and alter their frequency or wavelength before retransmitting them to Earth. The satellite's transponders are designed to handle different frequencies and can accommodate multiple channels at the same time. Depending on the intended applications and regulatory considerations, communication satellites operate in a variety of frequency bands. Different frequency bands, such as C-band, Ku-band, and Ka-band, are designated for specific purposes. Each frequency band has its own set of advantages and disadvantages in terms of signal propagation, bandwidth capacity, and regulatory constraints.
Voice calls, television broadcasting, internet connectivity, mobile communications, video conferencing, data transmission for businesses, and remote sensing are all supported by communication satellites. They play an important role in connecting people, businesses, and communities around the world, allowing for seamless communication across vast distances.
