Satellite technology is widely used and plays an important role in communication, remote sensing, weather forecasting and geological exploration. Among them, satellite communication technology can realize the functions of instant communication, radio and television transmission and Internet access on a global scale. Satellite remote sensing technology can obtain information such as topography, meteorology and vegetation in remote areas, and provide important data support for environmental protection and resource utilization of the earth.
Satellite has become a symbolic product of the construction of a powerful country, military strength and scientific and technological development. China has also developed rapidly in the field of satellites, and already has a series of satellite products independently developed, such as Beidou navigation satellite and Tianzhou cargo spacecraft. In the future, with the continuous progress of technology, satellites will continue to play an important role and become an important window for human beings to explore the universe.
