Breaking the technical blockade, core technology realizes autonomous and controllable

"Satellites are like high -precision eyes, overlooking the earth." Li Daren introduced that the laboratory participated in the construction of China's Beidou satellite navigation system. The Yami -level mobile phone navigation positioning system has the same level of accuracy of GPS, achieving centimeter -level real -time high -precision navigation positioning services.

Li Daren said that after these decade of efforts, the development of domestic software in the three generations of geographical information systems was successful. 85%of satellite remote sensing images of ten years rely on imports, and 85%of satellite remote sensing images are now self -sufficient.

"The development of surveying and mapping, navigation, and geographical information technology is not only the need for national defense construction, but also the need for serving economic development and serving the society and people's livelihood. Smart city, etc. "Li Daren said.

The "new star" born in the laboratory, borrowed from the smartphone design mode

"Luojia No. 3 is the world's first Internet high -resolution intelligent satellite that can be controlled by mobile apps." In the video connection, Li Daren specifically introduced this "new star" born in the laboratory.

Luojia No. 3 is a new generation of intelligent surveying and mapping remote sensing science test satellites. It is used to verify key scientific issues such as real -time acquisition, intelligent processing, and compression transmission of remote sensing data to explore the new model of remote sensing information services for Tianji's space network. Li Daren said that the satellite borrowed from the smartphone design mode. Users only need to send targets to the satellite to point latitude and latitude, countless windows, etc. Satellites can independently complete imaging task planning, image acquisition, orbit processing, image transmission, etc., to to to the image, etc. Personal user mobile terminal provides end -to -end real -time real -time image information services.

Li Daren said that promoting the construction of an information intelligent service system for the overall integration of air -heaven navigation, communication, and remote sensing can meet the needs of industries such as smart agriculture, smart cities, industrial Internet, sea and land transportation, etc.

I hope that Wuhan will catch the "special" and vigorously develop smart transportation and smart cars

Talking about the future development of Wuhan, Li Daren said: "Wuhan has rich science and education resources, well -developed transportation, and obvious geographical advantages. You can make full use of his" special long "to give birth to more distinctive new technologies and new industries, and strongly support smart transportation and smart cars. development of."

"We will adhere to autonomy, independence, and controllable to the people, based on the attitude of being responsible for the country and the people. Based on Wuhan, Hubei Wuhan, continue to overcome the technical problem of the" card neck '" Ziqiang made greater contributions to the country! "Li Daren said.
