CBERS-2

 2002-049A

---

The second ZY-2 was launched in Oct 2002 into a similar orbit to the first, and almost the same orbital plane. The orbit was raised to operational height between Nov 6 and 14, after which monthly tweak burns maintained the orbit. In Jan 2003, the satellites were 180 deg apart in their orbit.
