中国民营航天公司组建国内卫星数量最多商业气象星座

Core Viewpoint - Tianjin YunYao Aerospace Technology Co., Ltd. is establishing the largest commercial meteorological satellite constellation in China, named "YunYao Meteorological Constellation," which will consist of 90 self-developed satellites for global weather monitoring and forecasting [4]. Group 1: Company Overview - Tianjin YunYao Aerospace Technology Co., Ltd. is a private commercial aerospace company in China [4]. - The company aims to complete the satellite network by the end of 2026, with the constellation expected to become one of the largest commercial meteorological constellations in the world in terms of data production capacity [4][6]. Group 2: Satellite Details - The constellation will include 72 sun-synchronous orbit satellites and 18 low-inclination orbit satellites [4]. - As of now, 46 satellites have been successfully launched, with plans for 30 more launches this year and the remaining 14 to be completed next year [5][6]. - Each satellite costs several million RMB and weighs approximately 30 kilograms [7]. Group 3: Technological Capabilities - The completed constellation will form a high-resolution, high-precision, and full-scale atmospheric and ionospheric detection system [6]. - All 90 satellites will be equipped with global navigation satellite system occultation detection payloads, enabling the collection of atmospheric and ionospheric observation data, including temperature, humidity, pressure, and electron density [6]. Group 4: Industry Context - The YunYao Meteorological Constellation's occultation observation data ranked second in a radio occultation modeling experiment conducted by the European Meteorological Satellite Application Organization, indicating that the quality of its low-orbit satellite products has reached a world-leading level [7]. - The Chinese government has recognized commercial aerospace as a "new growth engine" and a "strategic emerging industry," highlighting its increasing importance [8].
