Fourth of the original Yunhai-2 sextet, contributing to China's radio occultation constellation for atmospheric and space weather sensing. The 2018 six-satellite deployment established the operational baseline for the Yunhai-2 program, which the World Meteorological Organization's OSCAR database now tracks as part of a broader 12-satellite Yunhai-2 constellation contributing meaningfully to global space weather monitoring, regardless of its underlying military sponsorship.
