Communication Satellites are used to communicate with the Earth’s data related to television and radio data. These Satellites are placed at a distance of 33900 Km from the earth.
What are Communication Satellites?
A communication satellite is an artificial Satellite that amplifies and relays the radio telecommunications signals via transponders. It establishes the multiple communications channel between the transmitter and receiver at different locations on the earth.
The Communications Satellites are used for the purpose of the radio, televisions, internet, telephones, and military applications. Till 1 January 2021, there are 2,224 Communication Satellites are present on the earth. Radio waves of high frequency are used for telecommunications links travel by line of sight and obstructed by the curve of the earth. The place where such Satellites are placed is known as the Geostationary Earth Orbit, to learn more detail about the geostationary orbit-
The satellites that were used to travel are known as the Orbit of the Satellite. There is multiple Satellites orbit where different Satellite is present in different orbits.
Types of orbits
Low Earth orbit (LEO)
This is a circular orbit, and the distance of this orbit from the earth is 120 to 2,000 Km
This is the orbit of the Satellites and the distance of orbit from the earth is 2,000 to 35,786 Km.
Geostationary Orbit (GEO)
This is the orbit where all the Communications Satellites are placed. The distance of this orbit from the earth is 35,900Km.
The Satellite in space will appear as a motionless object and the person who will look at the sky will say that it is a stationary object. The reason behind this is that the Satellite moves from the angular velocity of the earth.
The first geostationary orbit was launched on 19th August 1964, the name was syncome 3.
