Application of VSAT Satellite Communication System Technology

VSAT stations can easily form flexible and economical network systems with different scales, different speeds and different uses. A VSAT network can generally accommodate 200 to 500 stations, and there are broadcast, point-to-point, two-way interactive, collection and other application forms. It can be applied not only to developed countries, but also to countries with underdeveloped technology and backward economy, especially for those remote areas with complex terrain, inconvenient wiring and sparsely populated areas. Because it can be equipped directly to individuals, it also has important military implications. To sum up, VSAT technology can be applied in the following aspects.

1. The VSAT satellite communication system is used to popularize satellite TV broadcasting and satellite TV education, and transmit radio, TV, and commercial TV signals, especially for remote areas. This method can play a significant role in the construction of material civilization and spiritual civilization. effect.

2. The VSAT satellite communication system is used in financial and financial systems and securities systems to dynamically track and manage market conditions, greatly shortening the capital turnover cycle. The securities trading system uses the VSAT satellite communication system to carry out two-way communication with customers in all directions.

3. The VSAT satellite communication system is used for the management of water conservancy construction, monitoring hydrological changes, preventing and reducing the loss of natural disasters. The VSAT satellite communication system can transmit the information obtained by meteorological satellites, marine satellites, resource satellites and ground detection stations in time.

4. The VSAT satellite communication system is used for the management of transportation. Developed countries abroad have used the VSAT satellite communication system in the operation and dispatch of railways, which has greatly eased the tense state of transportation. With the VSAT satellite communication system, calls, telex and telegraph services between any two places can be easily carried out, saving money and time.

5. The VSAT satellite communication system is used in the military. During the 1991 Gulf War, the multinational force used the VSAT satellite communication system for a large number of mobile communications, and even equipped it to each soldier.

6. The application of VSAT satellite communication system in emergency communication and remote area communication. VSAT satellite communication system is the most convenient emergency communication backup system for natural disasters or sudden events, such as earthquakes.

VSAT is a small-diameter satellite terminal station. The "small" here refers to the small antenna diameter of the small station equipment in the VSAT satellite communication system, usually 1.2-2.4M. The use of this system for communication has the characteristics of strong flexibility, high reliability, convenient use, and the small station can be directly installed on the user side. The VSAT user data terminal can be directly connected to the computer to complete data transmission, file exchange, image transmission and other communications. tasks, thereby getting rid of the problem of ground interruption stations for long-distance communication. Using VSAT as a dedicated long-distance communication system is a good choice.
