Satellite communications. Illustration showing how communications signals can be transmitted over vast distances across the Earth using satellites. Microwave signal propagation is limited by obstacles and the curvature of the Earth. However, information can be transmitted to geostationary satellites using microwaves carrying digital signals. These signals are then re-transmitted as microwaves, either to another satellite, or back to parabolic receivers on Earth. | |
