How fast is Uranus moving in space?
Asked by Wiki User
Uranus revolves around the Sun at about 15,300 mph in its orbit, or about 4.25 miles per second. One might argue it is traveling much faster when considering the speed the solar system revolves around the milky way, the motion of our galaxy in the local group of galaxies, etc.
What is the name of the second satellite?
Asked by Wiki User
The name of the second satellite can vary depending on the context. It could be any specific satellite's name, such as "Hubble Space Telescope," "GPS satellite," or "ISS (International Space Station) satellite."
Why are satellites used to transmit TV programs?
Asked by Wiki User
There is an orbit called a geosynchronous orbit (GEO), which is a satellite that travels around the Earth in the Earth's exact speed, so it's always in the same position as the Earth. GEOs are used for communication nowadays, and so ground stations are always in contact with the satellites. That means that your T.V. programs and phone calls are never interrupted! :D
What happens to rockets gone into space?
Asked by Wiki User
A rocket has three parts all have tanks containing rocket fuel and oxygen. The first part lauches from earth than the secon part brings you closer the the targerted spot in space, The oxygen is needed because spase has no oxygen. Later the second part is released than the top containing the people is left with enough fuel to finish the job.

How long does a rocket travel?
Asked by Wiki User
Generally unguided rockets used as weapons do not travel as far as missiles, which is the term for guided weapons. Rockets used as fireworks only travel a few hundred feet vertically. Model rockets may reach a height of a mile or more. Rockets used to launch satellites propel the payload above the atmosphere, which expends most of their fuel.
Why is Satellite transmission used?
Asked by EncyofUSIndustries
Because satellites lack the geographic constraints of terrestrial systems, they are better suited for long-distance, point-to-multipoint transmissions such as television broadcasts
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 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!
