| The table lists all launches by China under the name Shijian together with any other satellites carried on the same launch vehicle. They have used a range of different launch vehicle types and have been launched from Jiuquan, Taiyuan and Xichang.
There purposes seem to be a range of technology demonstration and technology application missions with a leaning towards rendezvous, docking and grappling experiments. Shijian translates to English as "Practice".
They operate in a range of orbits from Sun-synchronous LEO to GEO.

Launch was already delayed by one day but reason not given. Replaced by Shijian 11-05, launched 2013 July 15. |

| Satellite involved in rendezvous tests, possibly as a satellite inspector. Following separation from the launch vehicle, it moved about 1750 km ahead of Changxin 3, another satellite carried on the same launch vehicle. It then made two close passes by it Aug 6 and Aug 9. Early on Aug 18, it pulled alongside another satellite already in orbit, Shijian 7 (2005-024A/28737), and shadowed it at less than 2km for about 48 hrs. It made further approaches to Shijian 7 later in 2013 and during 2014. |

| Secondary object in the Shijian 21 mission. Separated from Shijian 21 on Nov 1, probably around 15:00 UTC. On November 3, Space-Track gave it the name 'SJ-21 AKM' and classified it as a rocket body - the interpretation may be incorrect as it made small orbital changes about eight weeks after launch suggesting it was active at the time. |

| Test satellite described as "…scientific testing, technical verification". May be a satellite retrieval & disposal mission similar to Shijian 21 (49330/2021-094A) or may be a servicing/refuelling mission for Tianlian 1-03. Drifted around the GEO belt then settled close to Tianlian 1-03 (38730/2012-040A) at 20°.4 east on February 28. Started to drift away March 18 and stopped near 19°.8 east on March 29. Commenced move back towards Tianlian on Apr 15 but continued past it and started to drift eastwards away from it. Stopped near 174° east 2022 Oct 11. |

| Reusable, recoverable, spacecraft used to verify the design and engineering of the vehicle. Also carried a payload of several micro-gravity experiment including contributions from Pakistan and Thailand. Retro-fire October 11 at about 01:55 UTC led to touchdown at the Dongfeng landing site, near the Jiuquan Space centre, at 02:39 UTC. |

| Verification mission for a satellite refuelling and life extension system, aimed to link up with a satellite already in geosynchronous orbit. Arrived alongside TJS 11 (59020. 2024-037A) on Jan 14, possibly to conduct station-keeping tests but its eventual target seems to be Shijian 21 (49330, 2021-094A) - the two orbits are co-planar. |
