17 Jan 2022: China launched the classified Shiyan-13 (SY-13) payload from the Taiyuan Satellite Launch Center aboard a Long March 2D. The LM-2D inserted SY-13 into an unusual 357 by 1,297-kilometer orbit inclined by 98.7 degrees. Launch Video.

– China release no information regarding the mission or capabilities of SY-13. The CASC press release stated: “The Experiment No. 13 satellite is primarily used to conduct space environment sensing and related technology experiments.”

– Chinese state media also provided no information regarding the payloads or uses of Shiyan-13.

– China did place SH-13 in an orbital plane near the USA-245 (believed to be the last of the Block 4 KH-11 optical reconnaissance satellites).

– This orbital plane is also shared with Kosmos 2542 and Kosmos 2543 which are believed to be part of Russia’s Nivelir co-orbital ASAT program. Launched in 2019 Both Kosmos 2542 and 2543 have maneuvered to place themselves in positions to observe USA-245.

– Shiyan are understood to be a series of test satellites, with first launched in 2004. Shiyan satellite numbers are often non-sequential and have been developed by a range of entities, including the China Academy of Space Technology (CAST), CAS and the Harbin Institute of Technology (HIT).

– China currently has more than 10 Shiyan satellites in Sun-synchronous and GEO orbits. Shiyan-10, launched in Sep 2021, remains in a GEO transfer orbit (1,046 by 40,152 km inclined by 51 degrees) following an apparent anomaly affecting the satellite after launch.

The last launch was a pair of two Shiyan 12 satellites on December 23, 2021, on board a Chang Zheng 7A.

– CASC did reveal that a two-meter-diameter satellite-rocket separation device was used the first time with the Long March 2D due to special requirements of the satellite interface

– The Long March 2D series are scheduled to launch more than 15 times during the year, according to CASC. The rocket can launch from all three of China’s inland national launch centers at Jiuquan, Taiyuan, and Xichang. There were 6 LM-2D launches in 2021.
