ZIYUAN 3-02 (ZY 3-02) is a payload in SSO orbit, operated by State Surveying and Mapping Geographic Information Bureau / China Resources Satellite Applications Center (CRESDA), launched 2016.
Orbital data last updated 8 days ago. This may not reflect the current orbital state, not for operational use or collision avoidance. That number is the age of the measurement itself, not of our last check. We look for newer orbital data every six hours and publish whatever the tracking catalogue has released; when nothing newer has been released, the measurement below stays where it is. This is normal for this orbit. 3,183 of the 3,619 tracked objects in SSO were also last measured at least this long ago. Objects on this kind of path spend much of their time far from the ground sensors that track them, so they are re-measured far less often than something in a low orbit passing overhead several times a day.
