Guowang Family Analysis by LeoLabs (as of 23 Jan 26)

By Dr Darren McKnight, LEO Labs Senior Technical Fellow

Dr McKnight at LEO Labs has been doing some comparative analysis of Radar Cross Section (RCS) values across the growing family of Guowang satellites. Below is his report which concludes that China is launching slightly larger satellites into their 86.5° inclined orbits when compared with the satellites heading into their 50.0° inclined orbits. Thank you Dr McKnight!

China in Space reported on January 14, 2026, the Guowang satellites launched by the Long March (LM) 5B are larger than the satellites launched by the LM-12 or LM-6A. It was interesting that they did not mention Long March 8A even though there have been more Guowang launches using a LM-8A than any other variant (i.e., seven by LM-8A, six by LM-6A, four by LM-12, and three by LM-5B). An examination of the first 11 of the 19 batches of Guowang satellites does indeed show a differentiation in size of spacecraft but it does not exactly align with public statements. The table below summarizes radar cross-section (RCS) values for 86 of the on-orbit Guowang spacecraft during 2025. This RCS data is an aggregation of over 30,000 RCS measurements taken by LeoLabs.


Consistent with the public statement, spacecraft deployed by the LM-5B appear to be consistently larger (by about 30%) than the spacecraft deployed by the LM-12. There is also strong correlation between objects launched by LM-8A missions with those deployed by LM-12. However, the spacecraft deployed by LM-6A appear to be similar in size to the ones launched by the LM-5B. The difference is not large enough to be statistically significant, especially since the ranges (i.e., minimum to maximum) of RCS values have significant overlap between LM-5B and LM-6A missions.

In examining the table above, the stronger correlative factor does not appear to be the launch vehicle used but rather the inclination of the batch deployed; the payloads populating the 86.5° inclination planes are generally larger than the ones going to a 50.0° inclination.

While there has been speculation that Guowang has three vendors manufacturing Guowang satellites, if that is indeed the case, it makes sense that there might be two of the “high inclination” systems, however, we have only moderate in confidence in assessing two different types of satellites being launched into the planes with an inclination of 86.5°.

We have high confidence that the lower inclination deployments are currently using slightly smaller spacecraft than for the higher inclination planes and that LM-8A and LM-12 missions are deploying the same spacecraft.
