very small aperture terminal
Refers to a fixed satellite terminal whose antenna diameter typically does not exceed two meters. Also called VSAT.
A very small aperture terminal, is a two-way satellite ground station or a stabilized maritime Vsat antenna with a dish antenna that is smaller than 3 meters. The majority of VSAT antennas range from 75 cm to 1.2 m. Data rates typically range from 4 kbit/s up to 4 Mbit/s and sometimes up to a max downlink of up to 16 Mbit/s with some upgraded modules and enhancements. VSATs access satellite in geosynchronous orbit to relay data from small remote earth stations to other terminals or master earth station "hubs". VSATs are most commonly used to transmit narrowband data, or broadband data. VSATs are also used for transportable, on-the-move or mobile maritime communications.
