China's 156 satellites in Xingyan constellation to prevent collision

China is advancing its independent space traffic monitoring capabilities by developing the Xingyan (Star Eye) satellite constellation, which will ultimately include 156 satellites designed to track objects in orbit and reduce collision risks for commercial operators. Developed by Xingtu Cekong, a spin-off of geospatial data leader Zhongke Xingtu, the constellation aims to provide global coverage of low Earth orbit and focused monitoring of higher orbits, with updates every 30 minutes. The full system is expected to be operational after 2028, with 12 satellites planned for launch by 2027. This initiative complements China’s earlier launch of the Guangshi constellation, operated by Beijing Kaiyun United, which will consist of 24 satellites to enhance space situational awareness for both civilian and commercial use. These efforts reflect China’s goal to lessen reliance on foreign tracking data and improve the safety and efficiency of orbital operations amid the growing number of satellites and debris in space. The Xingyan system will employ AI-enabled sensors to detect debris,
