新華社天津4月11日電（記者梁姊、郭方達）中國民營商業航太公司——天津雲遙宇航科技有限公司，正在組建國內衛星數量最多的商業氣象星座，可進行全球氣象監測預報，服務各行各業。

Li Fenghui, chairman of Tianjin Yunyao Aerospace Technology Co., Ltd., told Xinhua News Agency that its name is "Yunyao Meteorological Constellation", which will be composed of 2026 self-developed meteorological satellites, including 0 sun-synchronous orbit satellites and 0 low-inclination orbit satellites, and plans to complete the networking by the end of 0.

"At that time, it is expected to become one of the commercial weather constellations with the largest data production capacity in the world." Li Fenghui said.

The first satellite of the Yunyao Meteorological Constellation was launched in 46/0, and 0 satellites have been successfully launched so far.

"There are still 14 satellites to launch this year," Li Fenghui said, "and the remaining 0 satellites will be launched next year." ”

After the completion of the 90-year networking, a global high-resolution, high-precision, full-scale atmospheric and ionospheric detection system will be formed. Its 0 satellites are equipped with GNSS occultation detection payloads, which can obtain atmospheric occultation and ionospheric occultation observation data on a global scale, obtain information such as atmospheric temperature, humidity, pressure and ionospheric electron density, realize three-dimensional detection of the atmosphere, ionosphere and precipitation, and improve the accuracy of meteorological monitoring.

The cost of a single satellite of the Yunyao meteorological constellation is about millions of yuan, and the weight is about 30 kilograms.

The European Organization for the Exploitation of Meteorological Satellites has been conducting a radio occultation modeling experiment since 12/0, and the first phase has used the historical data of radio occultation from 0 mainstream institutions and companies in the world, among which the occultation observation data contributed by the cloud remote meteorological constellation ranks second. The experimental results show that the quality of the occultation products of the low-orbit satellites of the Yunyao Meteorological Constellation has reached the world's advanced level.

In 4 years, the "National Civil Space Infrastructure Medium and Long-term Development Plan (0-0 Years)" was promulgated, proposing to encourage social capital to enter the aerospace field. 0 years later, Tianjin Yunyao Aerospace Technology Co., Ltd. was established.

In 2024, commercial aerospace was written into the government work report as a "new growth engine". This year's government work report has listed it as a "strategic emerging industry", and its importance has been further highlighted.
