Xinhuanet, Beijing, December 9 (reporters and Zhang Xinxin)-Lei Fanpei, Chairman of the China Aerospace Science and technology group said in an interview with Xinhua News Agency 9th, the next step will include 5 geostationary orbit satellites and 30 non-geostationary satellite compass global navigation satellite system consisting of, global positioning and navigation around 2020, implementing navigation and positioning services for a global audience. By then, China will be the third country to provide global positioning.
Lei Fanpei said that up to now, China has successfully launched its 4 Beidou navigation testing satellite and 16 Beidou navigation satellite, Beidou navigation project "three-step" strategy in the second goal, realization of the regional network. According to the plan, by 2020, will be built from 5 geostationary Earth orbit satellites and 30 non-geostationary orbit satellites, Beidou satellite global navigation system, provides global coverage of the high-precision, highly reliable positioning, navigation and timing services. After the completion of the system, will facilitate the formation of the industrial chain of satellite navigation, surveying, telecommunications, disaster mitigation and relief, and many other areas have significant economic and social benefits.
Civil-military integration, transformation and application of space technology for economic and social services is one of the direction of China's military in recent years. From the development of Europe's space industry, aerospace industry's direct input-output ratio is about 1:2 and related industrial radiation up to 1:7 to 1:14. Slightly lower the direct comparison of input and output of China's space industry in Europe and America, related industrial radiation can reach the range between 1:7 and 1:10. "That money invested more than 1 that can produce economic benefits of around 7. "Lei Fanpei think that in China, the civil-military integration of space and room is very large.
"For example, launch more navigation satellites, remote sensing satellites, communications satellites, weather satellites, etc, can also take advantage of developing rocket technology into civilian use, application for special equipment, satellite equipment and other services. "Investment in aerospace science and Technology Corporation, China Academy of launch vehicle technology management He Guosheng, Deputy Minister of the Department said.
Not long ago, China's "high marks, second" satellite into orbit, marking the China remote-sensing satellite into the Sub-m "high times". This satellite system in China with the highest resolution optical Earth observation satellites, accurate to 1 m spatial resolution for the first time. Means the satellite to the ground from more than 600 kilometers of space, can see the outline of 1 meter sized objects, we can distinguish the size of ground vehicles.
Lei Fanpei told reporters that will launch next year with high marks, third, fourth, and subsequent high points, fifth, and sixth, also will launch, providing higher resolution optical imaging.
In addition to launch a satellite carrier rocket, and China in enhancing the capacity for rapid access to space. "Such as the satellite network, has a bad, lets substitute satellites quickly entered, this requires a small launch vehicle development. "The International Academy of Astronautics (IAA), top aerospace awards granted by Karman prize winners, former General Manager of the China space industry Corporation Liu jiyuan.
Is China's Beidou satellite navigation system developed by global satellite positioning and communication system, is the United States global positioning system (GPS) and Russia global navigation satellite system (GLONASS) third after sophisticated satellite navigation systems.
It is understood that China attached great importance to development of socialization and industrialization of application of Beidou navigation system. The national satellite navigation industry medium and long-term development plan proposed that by 2020, China satellite navigation industry size will exceed 400 billion yuan. Beidou satellite navigation systems and their compatible products are widely used in important industries and key fields of the national economy, and gradually spread in the mass consumption market, contribution of domestic satellite navigation applications market is 60%.
China Association of satellite navigation and positioning, in 2013, China's Beidou industrial output value exceeding 10 billion yuan. Not long ago, the IMO Maritime Safety Committee at its 94th session on Beidou satellite navigation systems recognized safety circulars, which marks the Beidou navigation system officially become part of the global radio navigation system and achieved international legitimacy for maritime applications.
Enhance the overall development of the project as the big foundations, China North Industries Group official earlier told reporters that the network and part of the framework will be completed before the end of 2015 regional encrypted network reference station network up and running, provides m-precise positioning service completed before the end of 2018 regional encrypted network reference station networks across the country, provide more precise positioning service.
