A Very Small Aperture Terminal (VSAT) is a device - known as a small
private earth station - that is used to transmit & receive data
signal through a satellite.
The "very small" component of the VSAT acronym refers to the size of the VSAT dish antenna -typically about 4 feet (1.2 m) diameter- that is mounted on a roof, or placed on the ground.
This antenna, along with the attached low-noise converter (LNB-which receives satellite signals) and the transmitter (BUC-which transmits the radio waves signals) make up the VSAT outdoor unit (ODU), one of the two components of a VSAT earth station.
The satellite modem which makes the connection between the computer is named the indoor unit (IDU) and does all management of that small private low cost earth station.
The connection is quite similar in terms of speed to an ADSL connection. Sometimes referred to as Sat adsl or Satdsl or even dslSat.
