Space Application

1. Satellite remote-sensing. The fields and scale where satellite remote-sensing is used have been constantly expanded. Breakthroughs have been made in a large number of key application technologies; infrastructure facilities have been strengthened; the technological level and operational capabilities of the application system have been notably improved; and a national satellite remote-sensing application system has taken shape. China has built and improved the National Remote-Sensing Center, National Satellite Meteorology Center, China Resources Satellite Application Center, National Satellite Oceanic Application Center and China Remote-Sensing Satellite Ground Station, as well as satellite remote-sensing application and certification institutes of relevant state departments, provinces and cities. An optical remote-sensing satellite radiation caliberation station has also been completed and put into operation. Many remote-sensing products and services are provided by using data resources obtained from observation of the Earth by both Chinese and foreign satellites of multiple wavelengths of wide scope and long duration. Satellite remote-sensing application systems have been put into regular operation in many important fields, particularly in meteorology, mining, surveying, agriculture, forestry, land mapping, water conservancy, oceanography, environmental protection, disaster mitigation, transportation, and regional and urban planning. They are playing an important role in the nationwide land resources survey, ecological construction and environmental protection, as well as in major state projects, such as the South-North Water Diversion Project, the Three Gorges Project and the Project to Transmit Natural Gas from West to East.

2. Satellite telecommunications and broadcasting. Satellite telecommunications and broadcasting technologies are developing rapidly, their application is becoming more extensive and an application industry in this field has taken initial shape. By the end of 2005, China had more than 80 international and domestic telecommunications and broadcasting Earth stations, and 34 satellite broadcasting and TV link stations. Dozens of departments and some large corporations have established altogether some 100 satellite specialized communication networks and more than 50,000 Very Small Aperture Terminals (VSAT). The development and application of satellite radio and TV broadcasting services has increased the coverage and improved the quality of the programs all over China, particularly in the vast countryside. Satellite telecommunications and broadcasting technologies play an irreplaceable role in the projects "to give every village access to broadcasting and TV" and "to give every village access to telephones." A satellite tele-education broadband network and a satellite tele-medicine network have been established. As a member of the International Maritime Satellite Organization, China has established a maritime satellite communication network covering the whole world, ranking it among the advanced countries in the application of international mobile satellite communication.

3. Satellite navigation and positioning. China has implemented several major related projects, one of which is called "industrialization of satellite navigation and positioning applications." By employing domestic and foreign navigation and positioning satellites, China has made great progress in the development, application and services of satellite navigation and positioning technologies. The range and fields where satellite navigation and positioning are applied are being continuously expanded and the size of the national market for satellite navigation and positioning doubles every two years. Satellite navigation and positioning technologies have been widely used in transportation, basic surveying and mapping, project surveys, resources investigation, earthquake monitoring, meteorological exploration, oceanic surveys, and so forth.

Space Science

1. Sun-Earth space exploration. In cooperation with the European Space Agency (ESA), China has carried out the Double Star Satellite Exploration of the Earth's Space Plan. Together with the four space exploration satellites of the ESA, China's satellites completed the world's first joint, synchronous six-point exploration of the Earth's space, obtaining important data. Advance research into exploration of the lunar and the solar systems was also conducted.

2. Micro-gravity scientific experiments and space astronomical observation. China has carried out many items of experimental research in such fields as space life science, space materials science and micro-gravity science by using the Shenzhou spacecraft and recoverable satellites. It has also conducted trial tests of mutant crop breeding and high-power astronomical observation in space, and scored important achievements.

3. Space environment research. China has conducted research into space environment monitoring and forecasting, and made important progress in the observation, reduction and forecasting of space debris. It now has the ability to make forecasts of the space environment on a trial basis.
