      Geostationary Satellite

      Geostationary satellites are located exactly above the earth’s equator and revolve around the earth in a circular orbit. Their revolving speed and direction (west to east) are exactly same as that of the earth, which makes it look stationary from the earth’s surface. The exact altitude of these satellites above the equator is approximately 36,000

      Fixed Satellite Service

      Fixed Satellite Service (FSS) is a type of mobile telephone service that allows users in a specific area to make and receive cell phone calls. FSS systems or cell phone towers are placed in strategic, fixed locations and provide service to thousands of individual users simultaneously. Generally, FSS systems provide reception for several square miles

    • 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

      Ka Band

      The Ka band uplink uses frequencies between 27.5GHz and 31Ghz and the downlink uses frequencies between 18.3 and 18.8Ghz and between 19.7 and 20.2Ghz. The Ka band is branch of the K band from the electromagnetic spectrum. The term “Ka-band” is from Kurz-above, which originates from the German phrase “kurz” implying short. Ka band dishes

    • Uplink

      Uplink

      Uplink refers to a transmission of data in which data flows from a ground-based transmitter to an orbital satellite receiver. Uplink is used to send data to a satellite in Earth’s orbit in order to make changes to the way the satellite functions or simply redirect data to another ground-based receiver. Uplink is used in
