China Launches Guowang Group 21

8 Apr 2026: China launched a Long March-6A with the 21st group of Guowang (China SatNet LEO) satellites from Taiyuan. According to official sources, the 5 satellites (68656-68660) entered the preset orbit successfully. As with other Taiyuan launches, China placed the satellites into an 86.5° inclined orbit.

8 Apr 2026: China launched a Long March-6A with the 21st group of Guowang (China SatNet LEO) satellites from Taiyuan. According to official sources, the 5 satellites (68656-68660) entered the preset orbit successfully. As with other Taiyuan launches, China placed the satellites into an 86.5° inclined orbit. Group 21 is co-planar with Group 11, bringing the total number of satellites in that plane to 10 and matching the other five 86.5° planes. As of 9 Apr, 19 of 21 Guowang groups have reached their operational altitudes (only Groups 20 & 21 remain). Unlike the Qianfan constellation, all Guowang satellites have thus far reached their desired SMA. We will need to wait to see how China focuses its launch capacity for the remainder of the year. With a stated goal of reaching 310 satellites on orbit by 2027, I suspect we won’t have long to wait! Launch Video.

– With Group 21 there are now 168 satellites in the operational LEO Guowang constellation. Additionally, there are 3 Guowang satellites in GEO and China has launched 19 Guowang test satellites (see next article.)

– China is building out the Guowang constellation with orbits inclined either 50.0° or 86.5°. Currently there are 108 satellites in 12x 50.0° orbital planes (9 satellites/plane) and 60 satellites in 6x 86.5° orbital planes (10 satellites/plane).

– Launch Summary + number of days to target SMA…1,167.9km for 86.5° or 1,149.3km for 50.0°

Visualization of Guowangs 86.5° inclined orbits. China Launched Group 21 into near Co-planar Orbit with Group 11. Due to Group 20’s lower SMA its RAAN will shift west at a faster rate than Group 11. China will time SMA increases to result in Group 21 being co-planar with Group 11. Group 21’s RAAN is 30° east of Groups 4&9 and 30° west of Group 8 (well technically it is 330° west).
