  2. Satellite dish - Wikipedia

    en.wikipedia.org/wiki/Satellite_dish

    A satellite dish is a dish-shaped type of parabolic antenna designed to receive or transmit information by radio waves to or from a communication satellite. The term most commonly means a dish which receives direct-broadcast satellite television from a direct broadcast satellite in geostationary orbit.

  3. Automatic-tracking satellite dish - Wikipedia

    en.wikipedia.org/wiki/Automatic-tracking...

    Automatic tracking satellite dishes utilize gyroscopes, GPS position sensors, and uses unique satellite identification data and an integrated DVB decoder to aid in identification of the satellite that it is pointing at. The dishes consist usually of stepper motors to drive and aim the dish, gyroscopes to detect changes in position while the ...

  4. Universal Satellites Automatic Location System - Wikipedia

    en.wikipedia.org/wiki/Universal_Satellites...

    Universal Satellites Automatic Location System (USALS), also known (unofficially) as DiSEqC 1.3, Go X or Go to XX is a satellite dish motor protocol that automatically creates a list of available satellite positions in a motorised satellite dish setup. It is used in conjunction with the DiSEqC 1.2 protocol. It was developed by STAB, an Italian ...

    A Satellite Truck is a mobile communications satellite ground station mounted on a truck chassis as a platform. Employed in remote television broadcasts, satellite trucks transmit video signals back to studios or production facilities for editing and broadcasting. Satellite trucks usually travel with a production truck, which contains video ...

  6. Very-small-aperture terminal - Wikipedia

    en.wikipedia.org/wiki/Very-small-aperture_terminal

    A 2.5 m parabolic dish antenna for bidirectional satellite Internet access. A very-small-aperture terminal (VSAT) [ 1 ] is a two-way satellite ground station with a dish antenna that is smaller than 3.8 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Bit rates, in most cases, range from 4 kbit/s up to 16 Mbit/s.

  7. Communications satellite - Wikipedia

    en.wikipedia.org/wiki/Communications_satellite

    t. e. A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military ...

    Broadband Global Area Network. The Broadband Global Area Network (BGAN) is a global satellite network with telephony owned by Inmarsat using portable terminals. [1] The terminals are normally used to connect a laptop computer to broadband Internet in remote locations, although as long as line-of-sight to the satellite exists, the terminal can ...

  9. Transmit and receive integrated assembly - Wikipedia

    en.wikipedia.org/wiki/Transmit_and_receive...

    A transmit and receive integrated assembly ( TRIA) is used on a two-way satellite dish to process signals to and from a ground-based system and an earth-orbiting satellite. The TRIA is the part of the antenna which contains both the feed horn and the circuits which convert high-frequency satellite signals such as X-band, Ku-band and Ka-band to ...
