Satellite communication

Definition

Satellite communication refers to the use of satellite technology to transmit and receive data, voice, and video signals over long distances. This technology relies on satellites in orbit around the Earth, which act as relay stations to facilitate communication between different locations. In the context of space and underwater robotics, satellite communication is crucial for remote control, data transmission, and navigation, allowing robotic systems to operate effectively in challenging environments where traditional communication methods may be unavailable or unreliable.
