List of Yaogan Launches

Yaogan - China's Reconsats

Wednesday, Day 337

Maintained by:

The table lists all launches by China under the name Yaogan. They have used a range of different launch vehicles and have been launched from both Jiuquan and Taiyuan.

Yaogan seems to be a name to cover satellites having an imaging mission with a government or military purpose. Some seem to carry optical payloads and others carry radar. There are also some launches into orbits very like the US NOSS satellites. They probably have an ocean reconnaissance ELINT or SIGINT payload.

For the satellites in sun-synchronous orbit, looking at the orbit heights and inclinations together with the descending node local time gives an indication of related payload sets.

Yaogan 1 2006-015A 29092					in space
Imaging satellite (possibly carrying a synthetic aperture radar) for natural resources surveys and, possibly, intelligence gathering. Specific tasks include land survey, crop yield assessment, and input to disaster monitoring and prevention plans. Broke into eight fragments 2010 Feb 4, around 07:00 UTC as the result of a minor internal explosion probably due to equipment failure.
