The term VSAT (Very Small Aperture Terminal) refers to a type of standard antenna for satellite data communications.

Stated in a simply way, a VSAT terminal is a complete satellite station consisting of an outdoor unit (satellite dish + transmitter BUC +  receiver LNB ) and an idoor unit to be placed inside the customer premises (modem / satellite router ).

These stations will facilitate customer data communications via satellite link, either through private networks or simple Internet access.
