Detailed explanation-1: -A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.
Detailed explanation-2: -Communication satellites are also referred as Polar satellites. Polar satellites are those satellites that passes above or nearly above both the poles of the body orbited on each revolution and hence it has very close inclination of 90 degree’s to the body’s equator.
Detailed explanation-3: -Radio waves are used to carry satellite signals. These waves travel at 300, 000 km/s (the speed of light).
Detailed explanation-4: -Like in a relay race, where runners pass the baton to the next runner to run the next leg of the race, the Tracking and Data Relay Satellite (TDRS) works similarly with satellite’s information to transfer data between the ground and space.
Detailed explanation-5: -A communication satellite is an artificial satellite that transmits the signal via a transponder by creating a channel between the transmitter and the receiver at different Earth locations. Telephone, radio, television, internet, and military applications use satellite communications.
