Yaogan 14

 2012-021A

---

Launched with TT-1 (Tiantuo 1) from NUDT (National Univ of Defense Technology). RCS 5.8 sq m, similar to YW-5 and 12. However, the orbit, although similar, is more circular. The satellite makes frequent small manuevers. Its 1414 LTDN orbit was 60 deg from previous launches. YG-14 was reported to use the CAST PhoenixEye-2 bus but it had a larger fairing and Gunter Krebs’s website suggests it is a different payload.

CAST/CASTC DFH-3. According to sinodefense.com, this satellite was Shen Tong 1 and used for Ku-band mobile strategic communications.

\uni{ 神通一号}{ }

Mass 2300 kg. Served at 103E from 2003 to 2008, then at 98E.

In 2008, ZX-20 and ZX-22A exchanged positions `due to the needs of users'. In 2013, ZX-22A moved slightly and ZX-20 returned to the 103E position.
