Among them, the GNSS occultation meteorological detection systems called "Yunyao Xingzuo 04" and "Yunyao Xingzuo 05", which were independently developed by Tianjin Yunyao Aerospace Technology Co., Ltd. (hereinafter referred to as "Yunyao Aerospace" for short), were respectively carried by the "Zhong'an Guotong-1 Satellite" developed by Hunan Hangsheng Satellite Technology Co., Ltd. and the satellite developed by ZeroG Lab, and successfully sent to the space.

　　"This is the first time for Yunyao Aerospace to launch GNSS occultation detection system through simultaneous carrying by two satellites. It is a test of the team's batch production ability and new technology innovation ability," said Dr. Li Fenghui, general manager of Yunyao Aerospace.
