No. The purpose of Tianhui series are totally civilian.

The text and link below is an introduction for the Tianhui-1 series satelites.

The link do not say they are not military. TH & GF-14 are mapping sat for PLA. ZY-3 & GF-7 are civilian.

I think the Tianhui-4 should be the fourth generation of these series satelites.

No.
TH-1: First generation Stereo-topographic mapping satellite
TH-2: Microwave surveying satellite system based on InSAR technology
TH-3: Not launched but rumored to be a geosynchronous SAR satellite in IGSO orbit
TH-4: Probably second generation Stereo-topographic mapping sat

China launched TXJSSY-9(Telecommunication Technology Testing) satellite with a CZ-3B rocket in Xichang Satellite Launching Center, 00:43 UTC+8, Dec 30, 2021.

This is the 55th launch mission in 2021 and 405th CZ launch.

Missions complete. Goodbye, 2021.

Old news. Global Times is not a good source because it is often very late to reporting the latest developments on science or military related subjects.

The last sunset of 2021 from the perspective of the Fengyun-4A meteorological satellite.

It's civilian, trust me.

If it's for military purpose, you will not see any of the function description above.

Low-orbit 5G broadband communication satellite developed by the private firm Jiutian MSI Technology. A pre-production/factory-assembled unit has passed technical verifications. It will form a large constellation to provide high-speed 5G access on a global scale.

Some specs:
- Bandwidth: 10 Gbps
- Weight: 220kg
- Avoidance and altitude maneuvering capability (to dodge debris and other objects)
- Ka-band multi-beam antennas
- Modular design that enables the satellite to carry different payloads in the future, such as optical cameras to carry out earth observation.

Can be used in China's national 13,000-satellite mega-constellation in the future:

I'm not sure if this was posted already, but I've done a quick search and it didn't show up.

The Beijing-3 satellite's a 1-ton satellite with a 50cm per pixel resolution that can take photos of Earth very quickly.

The state of the art was WorldView-4, with a 30cm per pixel resolution but could only take photos much slower and with a narrower scope.

I say "was" because WorldView-4, launched in 2016, failed in 2019.

Of course these are all supposedly for civilian and commercial purposes and we really don't know what either Chinese or US spy satellites can do, but I found it interesting.

CCTV13 report, but on the SCMP youtube channel.
