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
it is used to transmit information from the provider to a requesting receiver.
No, TV stations do not broadcast their programs directly from space. Satellite communication technology is used to transmit signals from Earth to satellites in space, which then retransmit the signals to users on the ground.
Radio waves, microwaves, infrared and visible light can all be used for communication. Radio waves – are used to transmit television and radio programs. Microwaves – are used to transmit satellite television and for mobile phones. Infrared – is used to transmit information from remote controls.
Television satellites do not use infrared waves to transmit signals; instead, they primarily use radio waves, specifically in the microwave frequency range. These microwaves are effective for long-distance communication, allowing satellites to transmit audio and video data back to Earth. Infrared waves, while used in certain applications like remote controls and some optical communication systems, are not suitable for the large-scale transmission required by television broadcasting.
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.
In the Philippines, artificial satellites work as transmitters. These transmit cellular phone communications, Internet, weather observation, television channels' signals, and navigation.
Communication satellites: these are used to transmit television, radio, telephone, and internet signals. Navigation satellites: like the GPS system, these help determine location and provide accurate time information. Weather satellites: used to monitor weather patterns and provide important data for weather forecasting.
Almost 90 percent of public and private television stations transmit signals via satellite
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.
In television, electromagnetic waves are used to transmit audio and video signals from a broadcasting station to a receiving antenna on a television set. These waves carry the signals over the air, allowing viewers to watch programs on their TVs.
Digital satellietes transmit your tv stations to your dish network. When you have your dish or satellite tv set up to get digital stations, it transmits back from the satellite to your tv.
{| |- | Satellites are used for many purposes. Pictures of cloud patterns and other atmospheric events are used in weather prediction. They can receive and re-transmit all types of communications signals. This includes television, telephone calls and satellite radio signals. The can provide data that allows the Global Positioning Devices to pinpoint your current location. |}
