satelliidivõrke

Satelliidivõrke refer to networks of satellites used for various communication and data transmission purposes. These networks can encompass a wide range of satellite constellations, from geostationary orbit (GEO) satellites providing continuous coverage over a specific region to low Earth orbit (LEO) satellites forming constellations that offer global or near-global coverage. The primary function of satelliidivõrke is to facilitate the transmission of signals over long distances, bypassing terrestrial infrastructure limitations.

The technology behind satelliidivõrke involves a complex interplay between ground stations, user terminals, and the satellites themselves. Ground stations are responsible for sending commands to and receiving data from the satellites, while user terminals are the devices that access the network, such as satellite phones, modems, or dish antennas. Satellites act as relays, receiving signals from one point on Earth and retransmitting them to another. Different types of orbits are chosen based on application requirements. GEO satellites are ideal for broadcasting and constant connectivity, whereas LEO constellations are often employed for broadband internet services due to lower latency.

Applications of satelliidivõrke are diverse and expanding. They are crucial for global telecommunications, enabling phone calls and internet access in remote or underserved areas. Furthermore, these networks play a vital role in navigation systems like GPS, weather forecasting, scientific research, Earth observation, and military communications. The development of new satellite technologies, including smaller, more numerous satellites and advanced propulsion systems, continues to enhance the capabilities and accessibility of satelliidivõrke.
