SECM/Shanghai Engeneering Centre of MicroSat(

)is the other name of 中科院微小卫星创新研究院 (CAS microsat innovation and research academy). It is the researh arm of CAS, not a factory. Gesi's main founder is 上海中科辰新卫星技术有限公司 which is CAS' branch. So Gesi is partially owned by SECM probably the lead owner. So altough I am not sure but I am afraind that the 324 per year in the article is the same thing of Gesi.

This kind of double or tripple cunting happens a lot in China's news due to the crossing ownership and every individual entity or branch wants to boast their achievement in PR.

One thing to remember is that many Chinese state research institutes established commercial companies as their front ends to the market. We may recieve reports of the same thing from two seemingly different and unrelated entities and be lead to double count.
There are two distinct production lines, Gesi is in the "G60 Satellite Internet Industrial Base" in Songjiang district, Shanghai, SECM's production line is in Lingang new Area of the Pudong District of Shanghai.

Gesi's factory is fully dedicated to Qianfan while SECM's factory in Pudong district is shared for various projects.

The idea of SECM/Microsat as only a "research arm" may be outdated, it has been one of China's leading satellite manufacturer for the past few years and in scale is currently third only to CAST and SAST in China.
It went from less than 30 satellites produced from 2003 to 2022 to 150 produced since 2022.

A brief summary of the Jilin remote sensing constellation and Changguang, its parent company/operator.

The constellation now has 138 satellites in operation and can revisit any spot 35 to 37 times per day. Changguan has also put into operation phase I of its satellite production base, which occupies 97,300 sqm and has an annual production capacity of 100 satellites.
