How does satellite communication take place?
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..

Satellites and their uses
Geostationary and Polar satellites are two types of artificial satellites.
Geostationary Satellites are used for Communication purposes that include television, radio, satellite phones.
Due to these reasons, they are known as telecommunication satellites..
Satellites and their uses
Satellites operate in three different orbits: low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary or geosynchronous orbit (GEO).
LEO satellites are positioned at an altitude between 160 km and 1,600 km (100 and 1,000 miles) above Earth..
Where do satellite signals come from?
A signal is produced or reflected from a focal point.
This signal then reflects off the large part of the satellite dish and travels towards the satellite.
At the satellite, the signal reflects off another curved reflector towards a focal point where the signal is received..
Where is satellite communication mostly used?
Satellites provide in-flight phone communications on airplanes, and are often the main conduit of voice communication for rural areas and areas where phone lines are damaged after a disaster.
Satellites also provide the primary timing source for cell phones and pagers.Feb 13, 2014.
Where is satellite used?
A satellite is any object that orbits something else, as, for example, the Earth orbits the sun.
There are hundreds of satellites in operation.
They are used for diverse purposes such as weather forecasting, television signal, amateur radio and internet communications and the Global Positioning System..
Where is the satellite communication taking place in our atmosphere?
Many communications satellites are in geostationary orbit 22,300 miles (35,900 km) above the equator, so that the satellite appears stationary at the same point in the sky; therefore the satellite dish antennas of ground stations can be aimed permanently at that spot and do not have to move to track the satellite..

Where the satellites are located?
The satellites are positioned 22,300 miles above the Earth's surface in order to view the Earth's full disk and to maintain their geostationary orbit.
Geostationary satellites travel at about 7000mph in order to maintain their geostationary orbit..
Which way is used in satellite communication?
Note:The space wave, sky wave and ground wave are types of radio communication.
The space and sky wave may appear to be similar since both are types of radio wave propagation but only space wave propagation is used for satellite communication as space waves transmit signals to the troposphere..
