Recently, there has been a hot topic. What should China do with Musk’s Starlink plan?
Before answering this question, let’s take a look at what medicine is sold in the Starlink Project Gourd?
Musk said that the Starlink project is just a project to provide fast wireless networks for remote areas around the world. In order to make the network more smooth and faster, 12,000 satellites will be added before 2024. In the longer-term plan, This number will increase to 420 million. To put it bluntly, the Starlink project is a global WIFI service project that allows you to use data everywhere, even in remote places. Of course, in order to make the network smoother, there must be more in the sky. Satellites help information transfer, which is like a 5G base station on the ground. The more base stations, the better the signal.
Some people have said that SpaceX Starlink is no problem for commercial use, but if it is used in the military, it can interfere with ground receivers, monitor other countries, and increase US remote military control. The result is to strengthen the United States. Military control power poses a threat to other countries. Some people say that once Starlink matures, who will use 5G? China’s painstaking 5G strategy will not be ruined.
In fact, for most of us, the reason why we are so concerned about the Starlink project is not because we are curious about its technology, but because we are more concerned about the potential threats this project has to us. After all, everyone can’t understand Zainiu’s technical details, but I think that there are tens of thousands of satellites flying over my head all the time and monitoring myself all the time. This is an inexplicable fear and anxiety.
In fact, such concerns are reasonable. Judging from the fact that Musk has participated in the procurement bidding for the US military’s communications services, Starlink’s use in the military field is already a matter of high probability, which is also an important means of profit. However, someone in the industry explained that Starlink satellites are currently only used for broadband services for the military. Because their frequencies are fixed ku and ka segments, they do not have the ability to quickly track broadband and therefore do not have military means. Electronic interference capability.
In fact, in terms of transmission speed, if the “Starlink” and 5G bear the same use requirements, then 5G can hang on the Starlink in terms of transmission speed. And in actual use, the starlink must have a longer receiving antenna. This has led to the use of Starlink to be different from 5G. Let’s start with a brainstorm. If you really want to use Starlink signal on your mobile phone, will the mobile phone with antenna come back?
However, the benefits of Starlink are also obvious. Just like Musk said, WIFI can be used in remote areas, or places where 5G cannot reach. If this is replaced by the construction of base station buried optical cables, it is really a big project.
Back to the question at the beginning of the article, what should we do?
I think first of all, we should increase the capacity of Chinese satellites in low and medium orbits and make a good aerospace technology reserve. Space resources are limited, and occupy a little less. There is no internationalized space rules yet, and it is still first come first served. Therefore, satellite expansion is a strategic matter, which is bound to be related to the future space control rules formulation discourse. Right issue.
In addition, there is still a “generational gap” with the international advanced level in cutting-edge technologies such as rocket thrust and carrier recovery and reuse. In fact, in terms of rocket thrust, the largest thrust of the Long March series of carrier rockets I have passed is only equivalent to that of the United States in the 1960s, and the gap is not small. Further research is needed in terms of safety control technology for the landing zone of the grid rudder separated body, the rocket engine’s ability to start multiple times and the technology of continuous variable thrust in a wide range.
Fortunately, in 2019, my country’s Long March 2C carrier rocket has successfully carried out the safety control technology test of the grid rudder separation body landing zone, becoming the second country in the world to master this technology.

On April 20, 2020, the National Development and Reform Commission included satellite Internet in the category of “new infrastructure” for the first time, marking that the “satellite Internet” has risen to a national strategic level. In order to welcome the coming era of space-based Internet of Things, my country formulated the “Five Cloud Projects” of super projects in 2018, namely Xingyun Project, Hongyun Project, Feiyun Project, Kuaiyun Project, and Tengyun Project. All dimensions and aspects have carried out scientific planning for the development and utilization of space resources. You can do your own homework for the content of specific projects.
Although China’s aerospace industry started late, after years of astronauts’ efforts, the gap between us and the United States and Russia has become smaller and smaller. In some respects, we even surpassed them. So for ordinary people, how can we support the development of the country’s aerospace industry? In fact, doing one’s own job well and exerting one’s own value in one’s job position is already the best support. When the country is prosperous, it must be the day to become a powerful aerospace country. Finally, I wish our motherland an aerospace soon. Strengthen the country!
