How Does a Satellite Transmit a Signal?
An Integral Technology Satellites have been an integral technology for communications for many years. These large devices are able to maintain orbit around Earth and other celestial bodies because the speed in which they move, or their momentum, is able to keep up with or be balanced with the force of gravity. From government spying to applications like Google Earth and satellite radio and TV, satellites have many uses. Electromagnetic Waves Satellites utilize directional electromagnetic waves to transmit their signals. Such directional electromagnetic waves are used in many other modern applications and devices–microwaves among them–so this form of technology is hardly new. Radio Signals For many purposes, especially in technologies that are designed for the consumer, such as satellite TV or radio, geostationary satellites are utilized, named thus because they stay in the proper geostationary orbit, or in other words, look from Earth as if they remain in a fixed position because the
