| Probably military in nature and maybe intended for signals intelligence gathering (SIGINT). Initially in co-orbit with TJS-3 payload 2 and was probably attached to it on arrival at their original GEO station. Commenced eastward drift 2019 May 20 to begin a stop-start journey around the geosynchronous belt. From 2019 Sep - Dec, it stopped alongside Shijian 13 (42662/2017-018A) at 111° east, then 2020 Feb - 2021 Aug it was co-located with Shijian 20 (44910/2019-097A) at 88° east before commencing a westward drift. 2021 Oct it settled near 59° east alongside 2018-110C from where it had originally departed, remaining there until 2022 Jul 5. Continued to follow GEO belt and made further stops 2022 Sep 13 at 88° east near USA 233 (38070/2012-003A)) and 2023 Feb 8 at 137°.5 east near USA 298 (45465/2020-022B). |

| Communications technology test satellite. Not acknowledged in initial press reports of the launch but included in the China Aerospace Science and Technology Corp report of lift-off. Three days after launch, started to reduce its orbit height rapidly, losing about 20 km per day under the influence of a constant force - probably a continuously-acting thruster. The manoeuvre was completed Sep 14. |
