What Is VSAT?

by Contributor

A very small aperture terminal (VSAT) is a compact,satellite transmitting and receiving station. It is used mainly in data transfer and for setting up two-way Internet access.


Because of its size, a VSAT can provide satellite Internet service to companies, Internet cafes and even homes. The system reliably sends data, audio and video.

Outdoor Unit (ODU)

To receive and send data from the satellite, a VSAT must have an outdoor unit (ODU) consisting of a satellite dish which typically has a diameter of 3 to 5 feet. The dish must be placed in a high and open space, such as the roof of a building.

Indoor Unit (IDU)

Data received and sent from the ODU goes through a cable to the indoor unit (IDU). The IDU processes data and acts as a intermediary between the ODU and the computer system using the VSAT.
