How far is satellites from earth?
Asked by Wiki User
satellite should be at least 42000Kms from center of earth .As the radius of earth is around 6370Kms ,the height reduces to 35000Kms.
What is the function of satellite communication?
Asked by Wiki User
The satellite is used to receive foreign broadcast from other network stations and send it home users
AnswerSatellite communication is a process where a radio signal is transmitted to a satellite above your horizon. That satellite rebroadcasts that signal, on a different frequency, either to a ground station, or to another satellite to be relayed further. It allows communications without any local infrastructure, such as wires, towers, or other equipment. All that is needed is a receiver/transmitter which operates in the correct frequency bands, and which has sufficient power and sensitivity to communicate with a satellite, and the satellites.
Satellite communication allowed the boats in the Volvo Round the World Ocean sailboat race to communicate with the race headquarters, irregardless of where in the world the boats were.

Differentiate between satellite communication and terrestrial communication?
Asked by Wiki User
satellite communication is used for long distance communication, in this signals are transferred from landlines to station , station to satellite and then satellite to station , station to destination.
while bts is used for short distance communication with help of bts towers and range of bts towers lies between 8-15km.
How do you unscramble satellite signals?
Asked by Wiki User
By getting a subscription for $12.95 a month.
Where can one purchase Iridium satellite phones?
Asked by Wiki User
Satellite Phones can be purchased in many places. The best place to find one at a great price is probably online. While online is the best there are some physical camping, hiking, climbing stores where one can find a satellite phone.

How signal is transmitted to the satellite radio and receive back to earth?
Asked by Wiki User
A satellite is like a mirror in the sky. Only instead of reflecting light, it "reflects" radio and television signals. There are receivers and transmitters in the satellite, so what it receives on one frequency (or channel) can be then re-transmitted back to earth on another frequency. Its like sending out signals from a tower that is many miles high to reach out to a bigger area. Only without the tower!
Is it possible to see artificial satellite in night sky?
Asked by Wiki User
Yes, that is often possible. Preferably go to an area without streetlights and watch the sky. You will soon see fast moving shiny objects. These are satellites.
