2) Applications of communications and broadcasting satellites

China has steadily promoted the applications of communications and broadcasting satellites, and has brought into being a market of certain scale. It has improved its satellite radio and TV network: in 2008 China established a satellite service platform to give every village access to direct broadcast and live telecasts. It also implemented satellite broadcasting and transmissions of China National Radio and China Central Television programs, and one channel program of provincial radio and TV stations, thus greatly increasing the radio and TV program coverage. China has strengthened development of its satellite tele-education broadband network and tele-medicine network, mitigating to some extent the problem of shortage of education and medical resources in remote and border areas. China has also strengthened its satellite capacity in emergency communications, providing important support for rescue and relief work and for major disaster management.

3) Applications of navigation and positioning satellites

China's applications of navigation and positioning satellites have embarked on the road of industrialized development, and are now developing at a high speed, and important progress has been made in developing navigation- and positioning-satellite applications. Through both domestic and foreign navigation and positioning satellites, China has been applying these technologies more broadly; as a result, the market for this industry has expanded rapidly. China strives to promote the application of its Beidou satellite navigation system, and the system has been used in transportation, sea fishing, hydrological monitoring, communications and timing service, power dispatching, and disaster reduction and relief.

8. Space Science

1) Sun-Earth space exploration

China has implemented the Double Star Program to explore the Earth's magnetosphere in concert with the Cluster Program of the European Space Agency (ESA), obtaining much new data and making important progress in space physics.

2) Lunar scientific research

Through lunar exploration projects, China has studied the morphology, structure, surface matter composition, microwave properties, and near-moon space environment, further enhancing its knowledge of the moon.

3) Experiments on microgravity science and space life science

Using the Shijian satellites and Shenzhou spaceship, China has carried out space experiments in life science, materials science, fluid mechanics and other fields under conditions of microgravity and strong radiation. It has also conducted experiments on crop breeding in space.

4) Space environment exploration and forecasting

Using Shenzhou and other spacecraft, China has explored the space environment's major parameters and effects, worked on space environmental monitoring and forecasting, and studied space environmental effects.

9. Space Debris

China has monitored space debris, and given early warnings against them, ensuring safe flight of Chang'e-1 and Chang'e-2 lunar probes, and Shenzhou-7 manned spaceship. China has steadily pushed forward its work on space debris mitigation, fully inactivating Long March rockets, and moving a few aging GEO satellites out of orbit. China has also worked on protecting manned spaceship from space debris.
