Yaogan - China's Reconsats


Tyneside, UK
2023 Jun 4
Sunday, Day 155

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.

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.

in space
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.

Possibly a radar-carrying reconnaissance satellite. Lost when the launch vehicle third stage malunctioned. Referred to as Yaogan 33 in Chinese press in what may have been a bureaucratic error. Name was subsequently re-used in a later launch. Local time at descending node would have been about 06:00.

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. Formation was set up Feb 24 after one month of phasing manoeuvres.

One of a triplet of simultaneously-launched satellites described as being for "electromagnetic environment detection and related technological tests”. That may indicate they are electronic intelligence gathering satellites. They will use orbital manoeuvres to settle themselves at 120° spacing around the orbit plane.

in space
Chinese government or military remote sensing reconnaissance satellite. One of three similar satellites carried on the same launch vehicle and orbiting in formation. Launched into the same orbit plane as the three Yaogan 35-02 (launch 2022-068) satellites so may represent an enhancement of the constellation.

NOTE: Until Oct 26, Space-Track identified this object as 54046/2022-133E.
