    Quasi-Zenith satellite orbit QZSS animation, the "Quasi-Zenith/tundra orbit" plot is clearly visible.The Quasi-Zenith Satellite System (QZSS) (Japanese: 準天頂衛星システム, Hepburn: juntenchō eisei shisutemu), also known as Michibiki (みちびき, "guidance"), is a four-satellite regional satellite navigation system and a satellite-based augmentation system developed by the Japanese ...

  4. Low-noise block downconverter - Wikipedia

    en.wikipedia.org/wiki/Low-noise_block_downconverter

    It is possible for moisture in an LNB to freeze, causing ice to build-up at very low temperatures. This is only likely to occur when the LNB is not receiving power from the satellite receiver (i.e., no programmes are being watched). To combat this, many satellite receivers provide an option to keep the LNB powered while the receiver is on standby.

  5. Satellite delay - Wikipedia

    en.wikipedia.org/wiki/Satellite_delay

    Satellite delay is the noticeable latency due to the limited speed of light, when sending data to and from satellites, especially distant geosynchronous satellites.Bouncing a signal off a geosynchronous satellite takes about a quarter of a second, which is enough to be noticeable, but relaying data between two or three such satellites increases the delay.

  6. Multiswitch - Wikipedia

    en.wikipedia.org/wiki/Multiswitch

    a Multiswitch with 16 outputs, the four cables from the Quattro-LNB enter on the left. A multiswitch is a device used with a dual or quattro LNB to distribute satellite TV signals to multiple (usually more than four) receivers from a single dish and LNB.

  7. Fibre satellite distribution - Wikipedia

    en.wikipedia.org/wiki/Fibre_satellite_distribution

    An eight-way optical signal splitter to feed eight virtual LNBs or further splitters from a single optical feed. While optical fibre has been used for telephone and Internet backbone data, and even for television and multimedia carriage for terrestrial cable, for many years, use for satellite IF distribution has been held back by considerations of cost and installation convenience.

  8. Molniya orbit - Wikipedia

    en.wikipedia.org/wiki/Molniya_orbit

    The orbit's name refers to the "lightning" speed with which the satellite passes through the perigee. [5] The first use of the Molniya orbit was by the communications satellite series of the same name. After two launch failures, and one satellite failure in 1964, the first successful satellite to use this orbit, Molniya 1-1, launched on 23 ...

  9. Output signal switching device - Wikipedia

    en.wikipedia.org/wiki/Output_Signal_Switching_Device

    Active signal is issued when both lines present 0 V; a single line presenting 0 V for a duration longer than the test pulses is sufficient to signal an event. Some related terms: Electrosensitive protective equipment (ESPE) - a device such as a light curtain, safety scanner, or gate position sensor. The ESPE has OSSD outputs.
