Refers to small earth stations, usually in the 1.2 to 2.4 meter range. Small aperture terminals under 0.5 meters are sometimes referred to Ultra Small Aperture Terminals (USAT's).
Very small aperture terminal (satellite service) is satellite communications system that serves home and business users. A VSAT end user needs a box that interfaces between the user's computer and an outside antenna with a transceiver.
Small earth stations with a satellite dish usually 4-6 feet in diameter used to receive high speed data transmissions; can also transmit slow-speed data.
An earthbound station used in communications of data, voice, and video signals, excluding broadcast television, consisting of two parts: a transceiver placed outdoors in direct line-of-sight to the satellite, and a device placed indoors to interface the transceiver with the end user’s communications device, such as a PC.
One-meter diameter satellite dishes used by remote sites, as opposed to the 3m dishes used by head office, in a satellite-linked network. The central office is able to broadcast or multicast data to the remote sites. In Europe, regulatory restrictions are gradually being lifted to allow two-way transmission. The US does not labor under the same protectionism and so has a flourishing VSAT community that allows the remote site to reply using the same link.
Networks designed for satellite communication.
A Very Small Aperture Terminal (VSAT), is a 2-way satellite ground station with a dish antenna that is smaller than 3 meters. VSATs are most commonly used to transmit credit card or RFID data for point of sale transactions, and for the provision of Satellite Internet access to remote locations.
