Types Of Satellites By Orbits, Functions, And Practical Uses
2023年3月22日 · The 5 main types of satellites based on their orbits are: low Earth orbit (LEO); medium Earth orbit (MEO); geostationary orbit (GEO); Sun-synchronous orbit (SSO); geostationary transfer orbit (GTO). Let’s dig deeper into the nature of these 5 different types of satellites’ orbits to learn more about their characteristics and potential uses.
Communications satellite - Wikipedia
A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military ...

Satellite Communication: Origin, Architecture, Working, Types
Satellite communication can be classified based on the type of satellites used: Positioned 35,786 km above the equator. Remain stationary relative to Earth's rotation. Used for TV broadcasting and weather monitoring. Commonly used for navigation systems like GPS. Ideal for internet services and mobile communication.
Broadcast satellites: broadcast television signals from one point to another (similar to communications satellites). Downlink - The transmission of information from the satellite. Many Earth Stations can be covered by one satellite beam footprint.
