    • Azimuth


      Azimuth is a measurement at an angle used in the spherical coordinate system. To find a point of interest, the observer creates a vector that is then projected in a perpendicular fashion onto a reference plane. The resulting angle between the projected vector and the reference vector located on the reference plane is the azimuth.

      MCPC (Multiple Channel Per Carrier)

      MCPC stands for Multiple Channel Per Carrier. MCPC is a form of satellite transmission where each carrier is utilized to transmit multiple channels. MCPC transmits multiple video or audio channels on one carrier by utilizing Time Division Multiplexing (TDM). The alternative to MCPC is SCPC (Single Channel Per Carrier). MCPC is used much more than

    • Spot Beam

      Spot Beam

      A spot beam is a beam of radio signals that is directed towards a specific area on the Earth’s surface. Spot beams are the opposite of broad beams, which are beams that are directed towards a large area of the Earth’s surface. While broad beams are used for general telecommunication and surveillance, spot beams are

      Satellite Systems

      The basic types of satellite systems include geostationary (GEO), Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and Highly Elliptical Orbit (HEO) satellites. There are also public and private satellite systems such as Television Receive Only (TVRO), Direct Broadcast Satellite (DBS), Global Positioning System (GPS), and multibeam satellite operations. Geosynchronous satellites orbit the Earth on

    • What is a BUC?

      What is a BUC?

      A BUC (Block Upconverter) is a device that converts radio signals from a lower frequency to a higher frequency. BUCs are used in satellite uplink transmissions in order to transfer data from a ground based unit to a satellite in orbit that will then be redirected to another ground based unit in separate location. Likewise,

    • L band

      L band

      L band is a fequency range between 390MHz and 1.55GHz which is used for satellite communications and for terrestrial communications between satellite equipment. The high frequencies utilized by C band, Ku band, and Ka band would suffer from high signal loss when transported over a copper coax cable such as an Intra-Facility Link. An LNB

    • GPS Jammer

      GPS Jammer

      GPS stands for Global Positioning System. It is used by individuals, commercial entities and the military for navigational purposes. GPS uses 24 satellites that orbit the earth and send radio signals. The GPS satellites work with a GPS receiver which today can be found in individual handheld units, car navigational systems, boat navigational systems, highly

    • Weather Satellite

      Weather Satellite

      A weather satellite is a satellite which is used by meteorologists to gather information about the weather. Weather satellites give meteorologists a view of weather patterns over a very large area. This enables meteorologists to track large weather patterns and make more accurate predictions of future weather behavior. In addition to visual monitoring, weather satellites

    • 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

    • How Satellite Images Are Made

      How Satellite Images Are Made

      Satellite images are taken by reconnaissance satellites that orbit the Earth at a relatively low altitude, between 300 to 600 miles (or 480 to 970 km). As the majority of today's satellites are custom made in order to accommodate particular needs of the designer, there is no standard on which photo imagery is based on
