天津云遥宇航科技有限公司
Yunyao Yuhang, also known as Yunyao Aerospace, is a Chinese commercial space company established in 2019, based in Tianjin. It focuses on developing a constellation of meteorological satellites, called Yunyao-1, to provide data for global weather forecasting, including potential short-term earthquake forecasting. The company arranges for its GNSS occultation and reflectometry payloads to fly on satellites of other firms and has contracted with Changguang Satellite Technology (CGST) for satellite development and launches. Yunyao Yuhang's activities include satellite constellation development, weather data services, and GNSS-RO/GNSS-R technology.
