Yaogan - China's Reconsats


Tyneside, UK
2017 Dec 16
Saturday, Day 350

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.

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.

However, its purpose may be ocean surveillance similar to the US NOSS triplet formations that orbited at a similar altitude and inclination. The ground track lies 75° to the west of Yaogan 9 (2010-009A/36413) so it surveys a similar area about five hours later. Precise launch time - 04:06:04.

Remote sensing satellite described as undertaking land resources surveys and crop yield estimation. However, its purpose may be ocean surveillance similar to the US NOSS triplet formations that orbited at a similar altitude and inclination. The ground track lies 75° to the east of Yaogan 9 (2010-009A/36413) so it surveys a similar area about five hours earlier. Precise launch time - 04:06:04.

Mission described the satellite as being "...used to conduct scientific experiments, carry out land surveys, monitor crop yields and aid in preventing and reducing natural disasters". The orbit altitude and Descending Node time are similar to the initial values for Yaogan 6 (2009-021A/34839) suggesting the new satellite may be a replacement for it, or supplementary to it.
