China: More Internet Technology Demonstrators

30 Dec: China continued to launch internet test demonstration satellites as it used a Long March-2C from Jiuquan. As with other internet demonstration launches there is confusion as to how many were actually on-board. While China announced the launch of a single “satellite,” the space catalog is tracking 3 objects, only one of which is listed “active” and the other two as “unknown.” For what it’s worth, the launch patch has 3 stars. Launch Video.

– The Chinese named the satellite(s) Weixing Hulianwang Jishu Shiyan (WHJS) which translates to “Satellite Internet Technology Demonstration Satellite,” or something similar.

– The launch placed all three objects into a ~940x930km orbit with a 50° inclination.

– More observations are required to determine if all three objects are maneuvering/operational.

– This launch appears to be similar to another WHJS launch (2023-095) on 9 July 2023. There was initial confusion regarding the number of satellites on that mission as well, with China announcing a single satellite, but actually 2 maneuvering objects were on board. That launch patch has 2 stars.

– Both launches used a LM-2C with a YS-1 upper stage from Jiuquan. However, the 30 Dec launch (2023-212) resulted in the payloads being deployed to a lower altitude (SMA 934.5km vs 1,111.4km). The inclinations are also different 2023-212 at 50° compared to 86.5° for 2023-095.

– China conducted 5 Internet Test Demonstrator launches in the last 6 months of 2023:

1. 9 Jun 2023: Longjian-3 satellite from Jiuquan using a KZ-1A. (471.9km/49.1°)

2. 9 Jul 2023: 2 WHJS satellites from Jiuquan using a LM-2C with a YS-1 upper stage (1,111.3km/86.5°)

3. 23 Nov 2023: Chuangxing-20 01,02,03 from Xichang using a LM-2D with SY-3 upper stage (1,104.2km/50°)

4. 5 Dec 2023: Unknown satellite from Yellow Sea using a Jielong-3 (913.3km/86.5°)

5. 30 Dec 2023: 3 WHJS satellites from Jiuquan using a LM-2C with a YS-1 upper stage (936.4km/50°)
