Satellite Communications
Satellite communications use electromagnetic waves, specifically radio waves, to transmit information between Earth and satellites in orbit. These waves can carry voice, video, and data signals over long distances. When you make a call or watch satellite TV, your device sends a signal to a satellite, which then relays it back down to a ground station or directly to another satellite. This technology enables global connectivity, allowing people to communicate and access information from virtually anywhere on the planet, even in remote areas where traditional communication infrastructure might be lacking.

Satellite communications involves using artificial satellites in space to send and receive signals for various forms of communication, such as television, internet, and telephone services. These satellites orbit the Earth and act as relay stations, capturing signals from one location and transmitting them to another, often across long distances. This technology allows people to connect and share information globally, enabling services in remote or rural areas where traditional infrastructure may not exist. Satellite communications are crucial for broadcasting, global positioning systems (GPS), and disaster response, ensuring reliable connectivity regardless of location.
