  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.

  4. Polar mount - Wikipedia

    en.wikipedia.org/wiki/Polar_mount

    A polar mount is a movable mount for satellite dishes that allows the dish to be pointed at many geostationary satellites by slewing around one axis. [1] It works by having its slewing axis parallel, or almost parallel, to the Earth's polar axis so that the attached dish can follow, approximately, the geostationary orbit, which lies in the plane of the Earth's equator.

    en.wikipedia.org/wiki/Google_Maps

    Google Maps is a web mapping platform and consumer application offered by Google. It offers satellite imagery, aerial photography, street maps, 360° interactive panoramic views of streets (Street View), real-time traffic conditions, and route planning for traveling by foot, car, bike, air (in beta) and public transportation.

  6. Line-of-sight propagation - Wikipedia

    en.wikipedia.org/wiki/Line-of-sight_propagation

    Line of sight (LoS) propagation from an antenna. Line-of-sight propagation is a characteristic of electromagnetic radiation or acoustic wave propagation which means waves can only travel in a direct visual path from the source to the receiver without obstacles. [ 1 ] Electromagnetic transmission includes light emissions traveling in a straight ...

  7. Satellite television - Wikipedia

    en.wikipedia.org/wiki/Satellite_television

    A number of satellite dishes. Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. [1] The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block ...

  8. Footprint (satellite) - Wikipedia

    en.wikipedia.org/wiki/Footprint_(satellite)

    The ellipses indicate the necessary antenna diameter for receiving in cm. The footprint of a communications satellite is the ground area that its transponders offer coverage, and determines the satellite dish diameter required to receive each transponder's signal. There is usually a different map for each transponder (or group of transponders ...

  9. 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.
