On September 5, 2025, at 19:39 local time, China achieved a successful launch at the Jiuquan Satellite Launch Center. Utilizing the Ceres-1 (Yaoshi-15) carrier rocket, it sent the 27th satellite of the Yunyao-1 series and the Eros Stay-and-Track Testing Platform (Eros On-Orbit Test Platform) into space. Both the satellite and the platform smoothly entered their predetermined orbits.

The 27th satellite of the Yunyao-1 series functions as a scientific experimental satellite. It is outfitted with a GNSS occultation detection payload. During its time in orbit, it will carry out technical verification and operational application demonstrations, providing crucial data support for fields such as atmospheric detection.

Yunyao Aerospace has set an ambitious goal. By the end of 2026, it aims to complete the launch and networking of 90 satellites from the Yunyao-1 series, which will result in the formation of a global networking constellation. At present, commercial meteorological small satellite constellations, exemplified by the Tianmu and Yunyao constellations, are starting to take on a defined form.
