– All 3 satellites are in a 450x432km 53.0° inclined orbit.

– As is normal for the Shiyan satellite series, China released little information regarding the mission or capabilities.

– However, renderings of at least one of the satellites were released on Chinese social media (see images).

– The 53.0° orbit is also very popular for Starlink and Kuiper satellites. Per SBMS, the SY-21 01-03 are nearly co-planar with dozens of Starlink and Kuiper satellites.

– One press release also noted that “Test 32 Satellite 02 was developed by the Institute of Microsatellite Innovation, Chinese Academy of Sciences, and is mainly used to carry out new space technology experiments…This mission is the 78th satellite launch mission of the Institute of Microsatellite Innovation of the Chinese Academy of Sciences. So far, 217 satellites covering communications, navigation, remote sensing, science, micro-nano and other fields have been successfully launched.”

– China has launched the LM-11 18 times, this was the 6th sea launch.
