Techopedia Explains Very Small Aperture Terminal (VSAT)
VSAT end users have a box that acts as an interface between the computer and the external antenna or satellite dish transceiver. The satellite transceiver sends data to and receives data from the geostationary satellite in orbit. The satellite sends and receives signals from an earth station, which acts as the hub for the system. Each end user is connected to this hub station through the satellite in a star topology. For one VSAT user to communicate with another, the data has to be sent to the satellite. Then the satellite sends the data to the hub station for further processing. The data is then retransmitted to the other user via a satellite.
