      LNB Tester

      Before you ask what an LNB tester is, you should know what an LNB is. An LNB is the receiving end of a satellite dish. LNB stands for low noise blocker; it is a device that essentially does what it says. It blocks low noise (frequencies) in order to receive higher frequencies in which satellite

    • VSAT (Very Small Aperture Terminal)

      VSAT (Very Small Aperture Terminal)

      VSAT (Very Small Aperture Terminal) is basically a two-way satellite ground station with a less than 3 meters tall (most of them are about 0.75 m to 1.2 m tall) dish antenna stationed. The transmission rates of VSATs are usually from very low up to 4 Mbit/s. These VSATs’ primary job is to access the

    • Backward Error Correction (BEC)

      Backward Error Correction (BEC)

      Backward Error Correction, also known as an “Automatic Repeat Request” is an error correction technique in which a receiving device sends a request to the source device to re-send information. Backward Error Correction is used in situations where some of the transmitted data has been lost or corrupted during transit and the transmitting device must

    • Feedhorn

      Feedhorn

      The feedhorn is the part of a satellite dish system which gathers the reflected signal from the dish and focuses it towards the LNB. It is a type of horn antenna that is deployed to convey radio signals between the transceiver and the reflector antenna. Horn antennas basically effect a transition between waves propagating through

    • TV-GPS Technology

      TV-GPS Technology

      TV-GPS is a technology from Rosum Corporation of California. Basically, it is a GPS tracking technology that makes use of television broadcasting signals to intensify or strengthen GPS signals. It is slated for use in urban areas where most people own a television (so the TV broadcasting signals are extremely strong) and where the regular

    • IFL (Interfacility Link)

      IFL (Interfacility Link)

      An IFL, or Interfacility Link, is a cable system that is used in facilities to connect an outdoor unit and an indoor unit. An outdoor unit refers to the satellite receiver or coaxial cable that connects a service provider to a company while an indoor unit refers to the coaxial cables, routers, or transmitters inside

    • Medium Earth Orbit

      Medium Earth Orbit

      Medium Earth Orbit (MEO) refers to a satellite which orbits the earth at an altitude below 22,300 miles (geostationary orbit) and above the altitude of Low Earth Orbit (LEO) satellites. Medium Earth Orbit represents a series of tradeoffs between geostationary orbit (GEO) and Low Earth Orbit (LEO). Medium Earth Orbit enables a satellite provider to

    • Transponder

      Transponder

      A transponder is an automatic electronic monitoring or control device that receives, cross-examines, amplifies and retransmits the arriving signal. It is primarily implemented in wireless communication. The word ‘Transponder’ itself is a combination of two words; transmitter and responder (occasionally abbreviated to TPDR, TR, XPNDR, and XPDR). A transponder works by receiving a signal on

    • GPS (Global Positioning System)

      GPS (Global Positioning System)

      GPS stands for Global Positioning System.  It refers to a system of satellites that constantly transmit a signal, and a GPS terminal that picks up those signals and calculates its position on Earth by measuring the distance between itself and two or more GPS satellites (by measuring the time it takes to receive the signals).

    • QPSK (Quadrature Phase Shift Keying)

      QPSK (Quadrature Phase Shift Keying)

      QPSK (Quadrature Phase Shift Keying) is a phase modulation algorithm. Phase modulation is a frequency modulation version where the carrier wave’s phase is modulated to encode bits of digital information in each phase change. The “PSK” in QPSK refers to the use of Phased Shift Keying. Phased Shift Keying is a form of phase modulation
