What is a very small aperture terminal?
Very small aperture terminal (VSAT) is used to receive and transfer information such as narrow connections, radio frequency identification (RFID) and data collection and data collection (SCADA). Its name came from a relatively small antenna bowl with a diameter of no more than 10 feet (3 meters). VSAT is commonly used for commercial purposes, such as credit card data transfer and stable communication infrastructure.
The data are usually transmitted from network cartridges to satellites that monitor regular orbit. When the satellites approach the satellite ground station, they transmit data to the ground. Data transmitted normally ranges from 56 kbit/s to 4 Mbit/s. It is then accepted by the Vsat using a transceiver that interprets the end user data.
very small terminal functions of the aperture as a miniature communication antenna that is able to interact with other Vsat. Can also act as a two -way satellite ground station and give information back to Oblíjesatellites. This allows real -time communication between the end user and the hub. Maritime communications, such as those installed on ships, are usually more complicated. Because the ship is not stationary, the terminal must constantly adjust its configuration to be in line with the satellite.
The average VSAT measures 34 inches (75 centimeters) to 3.93 feet (1.2 meters), which is reasonably portable. The setting of a very small aperture terminal is relatively simple and takes just minutes from assembly to operation. The cost of one terminal is much cheaper compared to traditional satellite antennas. This makes it ideal for places where the building of a large satellite antenna would be difficult.
and VSAT transmits data using a private layer-2 network, which makes security one of its advantages. The data data can be transmitted via the protocol accelerators on the antenna. Signal strength and inHowever, the liqueness of the bowl still affects the quality of transmission.
Topological distribution of a very small configuration system of the aperture terminal is generally classified into three types. Star topology uses satellite to send data to the terminal. Network topology uses a system of strategically distributed terminals to deliver data from a end user hub. Combined topology, on the other hand, uses Star and Mesh distribution by having satellite transmission data to the Network of the VSAT network, effectively increasing the network coverage area.
