Kaiyun-1

Kaiyun-1 (Jiazhou) was China's first commercial space situational awareness satellite, built by Beijing Kaiyun United to monitor the orbital environment, track satellites and debris up to geostationary orbit, and generate independent orbital position data to reduce reliance on foreign tracking data. It was the first satellite of the planned 24-spacecraft Guangshi constellation, designed to provide SSA coverage across LEO, MEO, and GEO.
