How Do Satellites Send Information?

Ask Us Questions

Satellite is any object that revolves around the Earth in a circular path. Satellites are used for navigation, weather forecasting, communication and many other purposes. A satellite is like a mirror that reflects signals sent by a dish from Earth and bounces them back down to another dish at another location, on or outside of the Earth. At both places, the signals are coded or decoded into a format or language that can be accessed and therefore read. If you look at a satellite, you will see a curved dish on it. This dish reflects signals from a central structure called the central horn. The satellite uses the central horn as well as receivers, antennas and transmitters to communicate and thus does not require cables.
