A few days ago, the "Interesting Solving South Guangdong Science Star" innovation first show of the "Interesting Solutions" series of popular science brands "Interesting and Moving the Dreams" series was launched at the 2022 China Innovation and Entrepreneurship Achievement Fair (referred to as the "ICBC") science popularization sector. Cao Jing, an expert in scientific communication experts in the field of Chinese satellite meteorological and president of the Guangzhou Women's Science and Technology Workers Association, will talk to you online with you the scientific research and scientific popularity and innovation journey of "Nanyue Science Star", and share the latest news of Nanyue Science Star.

On July 27, 2022, with my country's current largest solid-carrier rocket "ZK-1A" (ZK-1A), it was successfully launched at the Jiuquan Satellite Launch Center, and six satellites were sent to the scheduled track. Among them, the star experimental video of "Nanyue Science Star" is hot on the circle of friends: next to the blue planet, the vast universe, the small satellite is printed with its own name, and the red text "chasing the star to evoke the dream of scientific dreams "". These 8 words are Cao Jing's handwriting. Cao Jing participated in the design of the satellite popular science sector.

Why is this satellite named "South Guangdong Science Star"? Cao Jing introduced that this satellite is the first small satellite with popular science education function. It was independently developed by Shanghai Aerospace Space Technology Co., Ltd. based on the integrated application of heaven and earth. Width, low power consumption, light weight, low cost and other advantages.

Since August 28, 2022, the super typhoon "Hinnamnor" has been struggling. Shanghai Aerospace Space Technology Co., Ltd. (hereinafter referred to as Space Company) was deployed in advance. As early as 2021, it started independent research and development projects. On July 27, 2022, it successfully launched the spatial company's starting star -Nanyue Science Star. The GNSS-R (Global Navigation Satellite System-Reflection) of the Star is a typical transformation project of the scientific and technological achievement. On the day of the northwest Pacific area, the load load monitoring data is monitored, and the typhoon wind area is successfully locked.

As of now, Nanyue Science Star has received and analyzed the completion of the 8-view GNSS-R load L1-level transmission data covering the entire typhoon area, tracking and monitoring the trajectory trend of Typhoon No. 11 "Xuan Lannuo", which has obtained preliminary analysis As a result, it can provide reliable support for high -precision, quantitative typhoon tracking forecast.

Typhoon is one of the most affected natural disasters in my country. Star-carrying GNSS-R monitoring technology has a large reflection section, a large number of signal sources, all-weather and all-day, accurate time space information and other characteristics. Strengthening the large -scale and long -term emergency monitoring of the development process of strengthening and disappearing can assist the casualties and economic losses caused by typhoon disasters. In the future, the typhoon changes of the typhoon of "Xuanlan Nuo" will be continuously followed, and the wind speed changes in the sea surface during the entire super typhoon life cycle will be used to accumulate more scientific data and continuously improve the data processing platform.

Nanyue Science Star will also carry out research on ground counter -discovery application research on the ground, sea surface height, and sea surface floating oil, and comprehensively detect the elements of the water and environmental elements of the ocean, agriculture, and wetlands to promote the innovative practice of the integrated application scenario of the world. Economic value and prospects.

Focusing on the "Nanyue Science Star New Carrier", Cao Jing said that he also carried out aerospace education, including "Star -chasing Science Dream Series", "Dreaming and Achievement Science and Technology Star Series", "Growing up and improving the scientific literacy series".
