satellite networks

Satellite networks consist of orbiting satellites that transmit signals between ground stations, enabling communication across vast distances. These networks are used for internet access, TV broadcasting, GPS navigation, and military applications. Satellites relay data by receiving signals from one point on Earth and re-transmitting them to another, overcoming obstacles like mountains or remote locations where traditional cables are impractical. They operate in various orbits, such as geostationary (staying above the same spot) or low Earth orbit (moving quickly around Earth). These networks provide connectivity in global, often hard-to-reach areas, supporting seamless communication worldwide.
