VSAT stands for Very Small Aperture Terminal. It can be described technically as an intelligent earth station connected to the geo-synchronous satellite suitable for supporting a variety of two-way telecommunication and information services such as voice, data and video.
The main function of the hub equipment is to receive inbounds and formulate outbonds. The hub equipment can be sub devided into two groups namely unit NCU. NCU main function is to formulate TDM outbonds (1024 kbps) and a master control unit (MCU). MCU keeps the clocks of the VSATs in synchronism with the clock at the hub. In addition there are subchannel controls units (SCUS) to take care of the various VSAT installations through link control processor (LCP) cards.
