Who is the chief scientist of Beidou?

Who are the modern scientists in China?

1, Academician Qian Xuesen (1 91year 65438+February1day -2009 65438+1October 3 1 day) is known as. China is an aerodynamicist and systems scientist, one of the founders of engineering cybernetics, and has made outstanding contributions to science and technology in China.

2. Qian Xuesen (19111~ till now) is a famous physicist in China and a world-famous rocket expert. Born in Shanghai, a native of Hangzhou, Zhejiang Province,/kloc-0 joined China in August, 1959 with a doctorate, and was known as the "father of Chinese missiles". Qian Xuesen put forward an extremely important implementation plan for the development of rocket and missile technology in China.

3. Wang is a famous nuclear physicist in China, the founder and pioneer of nuclear science in China, a senior academician of China Academy of Sciences, the president of China Institute of Atomic Energy, and one of the four advocates of China's high-tech development "863 Plan".

Chief scientist of Beidou

1, Li Deren, Academician of China Academy of Sciences, Academician of China Academy of Engineering, Academician of International Eurasian Academy of Sciences, Photogrammetry and Remote Sensing Scientist, Professor and Doctoral Supervisor of School of Remote Sensing Information Engineering of Wuhan University, Director of State Key Laboratory of Surveying and Mapping Remote Sensing Information Engineering of Wuhan University, Dean of School of Environment and Surveying and Mapping of China University of Mining and Technology.

2. Having been engaged in space work for more than 30 years, Xie Jun has served as the deputy director and director of 504 Institute of the Fifth Academy of Aerospace Science and Technology Group, the chief designer of Beidou-2 navigation satellite, and is currently the deputy chief designer of Beidou-3 project and Beidou-3 navigation satellite.

3. According to Cai Yi, the chief designer of the national Beidou ground-based augmentation system and the chief scientist of China Ordnance Industry Group, the ground-based augmentation system will complete the second phase of the construction task by the end of this year, and Beidou's high-precision location service capability will achieve another leap. 2065438+September 2004, the national Beidou foundation reinforcement system was officially launched.

Does China Beidou have the ability of high-precision positioning service?

Beidou satellite navigation system consists of three parts: space segment, ground segment and user segment. It can provide high-precision and reliable positioning, navigation and time service for all kinds of users around the world, and has the ability of short message communication. It has initially possessed the ability of regional navigation, positioning and timing, and the positioning accuracy has reached decimeter and centimeter level.

China Beidou satellite navigation system has initially possessed the ability of regional navigation, positioning and timing, with positioning accuracy of10m, speed measurement accuracy of 0.2m/s and timing accuracy of10ns.

Poor positioning accuracy or no positioning. "At this stage, Beidou has achieved regional positioning, but it does not have global positioning capabilities. The difference of positioning effect between Beidou and GPS is mainly caused by the number and distribution of satellites.

At present, the accuracy of Beidou navigation system is very high, which has surpassed GPS, and the positioning accuracy can reach centimeter level. Not only is the positioning accuracy very high, but our Beidou system in China already has global communication and navigation capabilities.

The obligation to promote the Beidou system to serve the world and benefit mankind. The positioning accuracy of Beidou navigation satellite reaches meter level. After strengthening, it can reach decimeter level and centimeter level. It can fully meet the development needs of unmanned driving and precision agriculture in the new infrastructure era. One direction of Beidou application, combined with more new technologies, Beidou can do many things.

Beidou system has just completed the "global networking", and a Beidou pioneer died, which made the Chinese people feel sad. he is ...

1, the war shocked the whole world. Let's make up our minds to start building our own satellite system, and Beidou system was born under such a background. The construction process wasted a lot of efforts of the people of China. Although 1994 was established, the first two satellites are collectively called Beidou-1.

2, water conservancy, transportation, fisheries, exploration, forest fire prevention and national security play an important role; Provide open services and authorization services to provide more secure positioning, speed measurement, timing and communication services and system integrity information for authorized users. Covering the whole world, Beidou-3 global satellite navigation system was officially opened.

3. The second step is to start the construction of Beidou satellite navigation system in 2004, and by 20 12, the Beidou satellite navigation system covering the Asia-Pacific region will be built, with the ability of positioning, navigation, timing and short message communication services covering the Asia-Pacific region.

4. By 20 12, 14 satellites have been launched, basically forming a global network. By 2020, China has launched the 59th satellite and completed the overall construction of Beidou. During the construction period, 137 countries have signed cooperation agreements with Beidou satellite navigation system.
