What are some uses of satellites orbiting the earth?
The difference is in the tilt of the plane of the orbit relative to the Earth's equator, which is zero for geostationary and 90 degrees for polar-orbit.
Communications satellites transmit UV waves?
No- UV is ultraviolet light. They transmit radio waves.
How do satellites transfer information to television?
satellites must transmit all their information to the earth down .satellites transmit information gathered by their sensors during each contact with the ground station. They contact the station using a large dish antennae which is situated on earth, at the site of the ground station. During the contacts between the satellite and ground station the satellites usually transmit information about the state of its various subsystems abd its position in space.
How was the satellite invented?
The idea of an artificial satellite goes back at least as far as the prototype science fiction story "The Brick Moon". The idea that actual, real satellites could perform useful work goes back to about 1947, when science fiction author Arthur C. Clarke realized that satellites orbiting the equator at about 22,000 miles out, would appear not to move in the sky. You could aim an antenna at it and leave it. Thus you could make communications satellites that could transmit a signal from anywhere on Earth to anywhere on Earth, just by having 3 satellites spaced around the Earth. The first actual, real satellite was Sputnik, sent up by the Russians in the late Fifties.
What was Sputnik 1 and 2?
Sputnik 1 and Sputnik 2 were artificial satellites that traveled around the Earth. People thought that Sputnik 1 was spying on them, but all it did was transmit a simple tracking signal for 3 weeks.
Which satellite configuration allows you to transmit signals globally?
At least three geosynchronous satellites orbiting equidistantly from one another.

How did satellites improve?
The satellites are sent into outer space by rockets. They revolve around the Earth. Signals are sent up to the satellites which transmit them back to Earth, covering a much larger area in the process. It is because these satellites that you can see events such as cricket matches being played in England or West Indies live on your television. Telephone and computer signals are also sent to other countries through satellites.
Why is ultraviolet radiation not used to transmit information to and from communication satellites?

How fast can a telephone modem transmit data?
56Kbps
What are true of a geostationary weather satellite except that it?
Orbiting the Earth above the equator is true of geostationary weather satellites and they have infrared sensors to transmit images of the entire hemisphere continuously. All of those things are true except that while they are moving in orbit they appear motionless.

WHAT IS THE what is the Use of satellites in tv transmission?
it is used to transmit information from the provider to a requesting receiver.
How active satellite differ from passive explain with an example?
active satellites are receives the transmitted signal from earth ,amplify the signal and transmit it. it is also called as transponders. but passive satellites just receive and transmit the signal.itac as the reflector
