9 Jul 2023: Official Chinese news sources reported that China launched a Long March-2C with a new test satellite from the Jiuquan Satellite Launch Center in northwest China. China has released very little information regarding the payload, only saying the satellite “will carry out test missions for satellite internet technologies.” US space observers have noted 2 objects were actually placed into orbit, a conclusion supported by the presence of 2x satellites on China’s Big Red Board announcing launch success. Launch Video.

– The LM-2C was equipped with a larger than normal fairing, raising suspicions regarding the number of satellites on board.

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

– The 18 Space Defense Squadron (SDS) is reporting 2 objects in 1095 x 1117 km x 86.5, and 1095 x 1112 km x 86.5 deg orbits, respectively.

-Subsequent observations confirm both objects are maneuvering.

-The LM-2C was also equipped with the YZ-1S upper stage. This is the 5th time that particular upper stage has been used. The YZ-1S seems to be used to place payloads in higher energy orbits.

There were 2 similar launches in August 2021 & May 2022.

– The August 2021 launch was for the Yaogan-32A/B satellite pair, while the May 2022 launch placed 3 communications satellites into Low Earth Orbit (LEO). China also released very few details regarding either launch.

-The fairing size, use of the YZ-1S and the higher orbit likely indicates the satellites are more like the heavier

OneWeb or Iridium proliferated LEO spacecraft.

-OneWeb and Iridium satellites also orbit much lower than these Chinese test satellites, both at ~750km.

-China recently launched a Starlink-like satellite on 8 June 2023. The 18 SDS cataloged the Longjiang-3 in a 490 x 500 km x 49.1 deg orbit. This is less than half the altitude of the satellites launched on 9 July, and closer to the Starlink operational orbit of ~570km.
