About this launch

Hongyan-1 is the first demonstration satellite for Hongyan, which is a planned constellation consisting of 320 satellites in low Earth orbit. Yunhai-2 is a constellation of Chinese military meteorological satellites. Reportedly the satellites use Global Navigation Satellite System (GNSS) Radio Occultation (GNSS-RO) to collect atmospheric data for weather prediction and for ionosphere, climate, and gravity research.
