Yaogan - China's Reconsats


Tyneside, UK
2025 May 16
Friday, Day 136

Curated 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 missions.

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.

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 west of Yaogan 9 (2010-009A/36413) so it surveys a similar area about five hours later. Precise launch time - 04:06:04.

Imaging satellite 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. 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.

Yaogan
Radar Earth imaging satellite aimed at sun-synchronous orbit with LTDN 06:00. Lost when the launch vehicle third stage malunctioned. Referred to as Yaogan 33 in Chinese launch announcement in what may have been a bureaucratic error as the name was subsequently re-used in a later launch of a different design of satellite.

in space
Remote sensing satellite described as used for electromagnetic environment surveys and other related technology tests. Orbiting in close formation with the other two satellites from the launch, its purpose may be signals or electronic intelligence gathering over the world's oceans, a similar task to the US NOSS triplet formations that orbited at a similar altitude and inclination. Until 2021 Apr 8, this satellite was catalogued as 2021-020B/47855 - that ID now belongs to an item of debris.
