Ground terminals used for the reception and/or transmission of information to/from a communications satellite. Generally used in teleconferencing for the transmission and reception of video teleconferencing signals.
the ground equipment, including a dish and other electronics components needed to receive and/or transmit satellite telecommunications signals. An "uplink" is used for sending information to a satellite for distribution to various earth receiving stations, while a "downlink" is used to receive such information.
Hardware necessary to acquire data directly from environmental satellites. The WEFAX Earth station diagram illustrates a basic ground station configuration for obtaining direct readout data from geostationary environmental (weather) satellites.
An installation (antenna and associated equipment) located on the earth's surface and intended for communication with one or more satellites. The term is usually understood to refer to the ensemble of equipment that is needed to effect communications via satellite.
The term used to describe the combination of antenna, low-noise amplifier (LNA), down-converter, and receiver electronics; used to transmit and receive a signal by satellite. Earth Station antennas vary in size from the 2 foot to 12 foot (65 centimeters to 3.7 meters) diameter.
The antenna section of the Earth Segment or a Satellite telecommunications system. An Earth Station consists of a reflector (usually a parabolic dish), feed system to send and receive data, data handling equipment, and mechanical tracking equipment to keep the Satellite within the antenna's data send/receive area. Parabolic dish antennas come in two main varieties; regular and offset feed. Since a feed originates or collects the data, it has to be at the focus of the parabola, which is in the center of the data stream. This means that it obscures a large portion of data from the dish because of it's "shadow". For large dishes the relative amount lost is negligible, but for smaller antennas this "shadow" can have a massive effect on performance. To solve this, the feed is offset, or dropped out of the data stream. This has the added bonus of decreasing sidelobes. Earth Stations are owned by the company receiving the data from the Satellite network, and so need to operate within certain specified parameters, to maintain the network's stability. Some of these parameters are Sidelobes, Transmit Gain, Cross-Pol Isolation, Axial Ratio, Receive Gain, and G/T.
Combination of antenna, low-noise amplifier (LNA), down-converter, and receiver electronics used to receive a signal transmitted by a satellite. Earth Station antennas vary in size from the 65 cm to 3.7 m diameter size used for TV reception to as large as 30 meters in diameter sometimes used for international communications.
A station located either on the Earth's surface or within the major portion of the Earth's atmosphere and intended for communication: with one or more space stations; or with one or more stations of the same kind by means of one or more reflecting satellites or other objects in space.
The ground-based portion of a satellite communications system is called an earth station or a ground station. The station consists of an antenna and receiver (or transceiver) that are in communication with a satellite in geosynchronous orbit.
The term used to describe a satellite communication facility which includes the combination of an antenna, with an LNA or LNB, the down-converter, and the satellite receiver electronics used to receive a signal transmitted by a satellite. Satellite dish sizes vary from as small as .2 feet to as much as 100 feet. If you receive a satellite signal at your home via a satellite dish located on your premises you are considered an Earth Station in the broadest interpretation of the term. The actual designation of an Earth Station is usually reserved for sites that are capable of both transmitting and receiving satellite signals. Transmit/Receive sites are sometimes referred to as "Teleports".
A complete satellite receiving or transmitting station including the antenna, electronic and all associated equipment necessary to receive or transmit satellite signals. Also known as a ground station.
