A Shiyan-10 (02) satellite launched in late December and has similar orbital parameters to another Shiyan-10 satellite but with a different right ascension of the ascending node to increase northern-hemisphere visibility.
The first Shiyan-10 satellite launched from Xichang Satellite Launch Center on 2021-09-27.
The Shiyan-10 (02) launch followed the 2022-12-27 launch of Gaofen-11 (04) from Taiyuan Satellite Launch Center on a Long March 4B.
The China Aerospace Science and Technology Corporation (CASC) achieved a successful launch of Shiyan-10 (02) from Xichang.
A Long March 3B rocket launched Shiyan-10 (02) from Xichang Satellite Launch Center on 2022-12-28 at 11:43 p.m. Eastern.
After months of apparent inactivity between October 2021 and February 2022, Shiyan-10 performed a fuel-intensive maneuver to change its inclination and enter a Molniya orbit.
New orbital data from the U.S. Space Force’s 18th Space Control Squadron in late March 2022 showed Shiyan-10 in an approximately 1,853 by 38,878 km orbit with a 63.6-degree inclination.
Shiyan-10 initially entered a geosynchronous transfer orbit but was apparently unable to fire its main engines to reach geostationary orbit.
By mid-October 2021 Shiyan-10 had raised its perigee through small engine activity, indicating the satellite was active.
Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics tracked Shiyan-10 in a 51.1-degree orbit following small orbit-raising moves in late February 2022.
Shiyan-10 launched on a Long March 3B from Xichang Satellite Launch Center on 2021-09-27.
Shiyan-10, launched in September 2021, remains in a geosynchronous transfer orbit of 1,046 by 40,152 km inclined by 51 degrees following an apparent anomaly after launch.
Shiyan-10 is understood to have been targeting a geosynchronous orbit and currently has an apogee of 40,100 km.
Shiyan-10 has raised its perigee to 1,100 km, according to data from the U.S. Space Force’s 18th Space Control Squadron (SPCS).
New orbital elements published by the U.S. Space Force indicate Shiyan-10 performed small burns to raise its perigee to about 567 x 40,428 km.
U.S. Space Force’s 18th Space Control Squadron published data showing the Shiyan-10 payload entered a geosynchronous transfer orbit of 177 x 40,105 km with a 51-degree inclination.
Shiyan-10 was launched on a Long March 3B from Xichang Satellite Launch Center on 2021-09-27.
