VSATs are satellite communication systems that use small dish antennas

VSAT stands for Very Small Aperture Terminal, which is a type of satellite communication system that uses small dish antennas to transmit and receive data via satellites. VSAT technology is widely used for various applications, including internet connectivity, voice communication, videoconferencing, and remote sensing. VSAT systems consist of a hub station and multiple remote terminals. The hub station acts as the central control and communication point, while the remote terminals are located at customer sites or remote locations. VSAT systems use small dish antennas, typically ranging from 0.75 meters to 2.4 meters in diameter, depending on the required signal strength and geographic location. These antennas are designed to transmit and receive signals to and from the satellite. VSAT systems rely on geostationary satellites, which are positioned at fixed points above the Earth’s surface. The dish antennas communicate with these satellites, which relay the signals to and from the hub station. VSAT systems support two-way communication, allowing data to be transmitted in both directions—uplink (from remote terminals to the satellite) and downlink (from the satellite to the remote terminals). This enables interactive communication and real-time data exchange.
