Old news, Already confirmed GF-11 is 10cm GSD from academician Li Deren. I am just waiting for the next gen optical sat with 2-4m mirror

"So China seems to have accomplished a great leap forward in space optics. As GF-11 is positioned on a 247x693km elliptical orbit (and moves to a 470km circular later), a 1.7m mirror would give it a ground resolution of 8 to 10cm at perigee, at around 10AM local solar time and at 20°N, right over India and the South China Sea. [Resolution was in November 2020 by Academician Li Deren, and he said it is 0.1m, so the prediction was very close]. At the average altitude of 470km, the resolution is still 15 to 20cm, surpassing all commercial satellites and most reconnaissance satellites. This propels China into the select club of countries that can acquire satellite imagery, meaning the resolution is high enough to identify small hand-held weapons. Presumably the only members of this club are the US and now China, and that will continue to be the case in the foreseeable future, with maybe Russia joining them later if the program fulfills its promises."
Indeed. This report was written in 2018. While Beidou Navigation Satellites have gotten the most attention and PR, China's achievements in Earth observation satellites series meanwhile are no less impressive. They don't have as much report coverage due to their semi-secret nature.
