How fast is Uranus moving in space?

User Avatar

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.

Why are satellites used to transmit TV programs?

User Avatar

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

How long does a rocket travel?

User Avatar

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.

What is the function of satellite communication?

User Avatar

Asked by Wiki User

The satellite is used to receive foreign broadcast from other network stations and send it home users

Answer

Satellite 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.

How signal is transmitted to the satellite radio and receive back to earth?

User Avatar

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!
