Yes they are.
-To capture television signals -To receive the signal from the satellites
Broadcasting stations use television satellites to send their signals around the world.
Natural satellites are organic objects that orbit the earth such as the moon. Artificial satellites are objects humans propel through the earth's atmosphere in order to orbit the earth such as satellites for TV and radio signals.
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.
The Hot Bird satellites are operated by Eutelsat. They are used for broadcasting digital TV and radio signals to continental Europe and northern Africa.
In the Philippines, artificial satellites work as transmitters. These transmit cellular phone communications, Internet, weather observation, television channels' signals, and navigation.
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.
well heres one answer- its possible the aliens out there are interfering with our equipment! Hows that for an answer!
The purpose for having communication satellites in space, is by providing telecommunication throughout the world. Communication satellites are mostly used for mobile phone signals, weather tracking, and broadcasting television programs.
i should imagine its because EM waves can travel through a vacuum so that's why it is possible for satellites to broadcast information from impulse signals sent from outer space
