First of all, Beidou technology and satellite launch must be done by the state. Secondly, is this field corporatized? Which company is it? Such as China satellite and northern navigation. Thirdly, there is no special central enterprise Beidou company in listed companies. Big Dipper, China Haida and Zhenxin Technology are not central enterprises. SuperMap software and Siwei Tuxin are the prefixes of China, but they are not the leading position of Beidou. How's it going? How about a compliment?
