On August 17, CCTV’s “Dialogue” interviewed Wang Yang, CEO of Zhongkong Daoyu. The following is the transcript of the conversation.

Host: Mr. Wang, this satellite on the screen is your target, right?

Wang Yang: Yes. What we are doing is to send satellites into space and build a global low-orbit communication constellation. We are currently launching 72 satellites into a 600-kilometer low-altitude orbit. After these 72 satellites are deployed, they can provide satellite network signal coverage anywhere in the world except the North and South Poles.

Host: What is the difference between this low-orbit satellite and an ordinary satellite?

Wang Yang: For example, the live broadcast signals of the current Paris Olympics are generally transmitted via high-orbit satellites. From the surface of the earth, there is a geosynchronous orbit about 36,000 kilometers above the earth, and three high-orbit satellites can cover the entire surface of the earth. However, with the development of technology, we have found that satellites can play a greater role in the low-orbit area of ​​300 to more than 1,000 kilometers. For example, it may take 240 milliseconds of delay to communicate with a high-orbit satellite, but it only takes 20 milliseconds to communicate with a low-orbit satellite. The overall transmission efficiency and delay of a low-orbit satellite are even better than those of ground optical fibers. At the same time, it can cover places that our ground base stations cannot cover.

Host: Mr. Wang, you just said that three high-orbit satellites can cover the world, so is it necessary for us to build 72 (low-orbit satellites)?

Wang Yang: It is precisely because the cost of high-orbit satellites is too high. We need at least 1 billion RMB to build a high-orbit satellite, and its launch cost is also very expensive. If it is a low-orbit satellite, its price will drop by one or two orders of magnitude, and it is safer. The failure of any satellite will not affect the reliability of the entire communication. The capacity of low-orbit satellites will be larger and the speed will be faster. One of the problems we often encountered before is that the human ground network is so perfect, with optical fiber, base stations, and core networks. The ground network it has established can even provide network signals at the base camp in the Himalayas. But the real situation is that 94% of the world has no signal coverage. In the world, our understanding of the blue planet is still far from enough.

Host: Is it worth it for us to spend money to provide radio signals to places where there are not many people?

Wang Yang: This should be an inevitable trend. Humans will continue to expand the boundaries of space, such as conquering uninhabited areas, and even going beyond the Earth to travel to the stars. With satellites, whether our friends are in the desert, on the island farthest from the mainland, or even traveling in the future, our mobile phones, cars, and aircraft can all be connected to data everywhere.

Host: When will we be able to achieve the goal of launching 72 satellites?

Wang Yang: We should be able to complete the deployment of 72 satellites in about 12 months. (After the deployment of the third-orbit satellite is completed) we will provide commercial services to the world. In fact, we have reached a stage where applications are being put into practice.

Host: (Compared to the long cycle of other future industries) Yours only takes one year?

Wang Yang: Actually not. We have experienced 10 years of continuous entrepreneurship, and most of our team members have accumulated nearly 20 years of experience in the entire aerospace field.

Host: Do you have any longer-term goals?

Wang Yang: In the second phase, we will focus on the establishment of a low-orbit communication constellation of 300 satellites. The low-orbit space is already very crowded, with more than 6,000 Starlink satellites operating at 300 to 500 kilometers, so it is urgent to occupy the frequency and orbit positions in the entire space.

Host: We have the impression that artificial satellite technology is relatively mature. Are there any scientific shortcomings in your field that need to be addressed?

Wang Yang: In fact, aerospace itself is a system engineering, not a theoretical study. For example, the theoretical system of all the aircraft designs we are involved in now was very complete 100 years ago, and the current engineering cycle is just different.

Host: If you want to widen the gap with your peers, do you need to build a moat in certain areas?

Wang Yang: This is indeed necessary. We have established our own moat in the layout of the industrial chain of commercial aerospace and the commercialization of the landing. The landing of large-scale commercial applications has always been a difficulty in the development of commercial aerospace companies. We have taken the lead in achieving breakthroughs in this regard. I brought a self-developed satellite communication chip, which uses the industry-leading 22nm process. This chip is actually used in our current mobile phones. We have launched a constellation of low-orbit communication satellites for satellite communications. How do we use it on the ground and how do we demodulate our signals? We will implant this 4mm chip into existing mobile phones, and use the mobile phone antenna to transmit satellite data.

Host: It sounds like our goals are very ambitious. Can other industries or other supporting facilities keep up? Are they too advanced?

Wang Yang: I think what we are doing now is actually achievable based on China’s entire industrial foundation. Our team used to have many people from the national team, as well as some experts from the Chinese Academy of Sciences. At the beginning of the business, we repeatedly reminded ourselves that the probability of scientists dying in entrepreneurship is extremely high, and it may even be a disaster to some extent. Therefore, when we consider the entire business rhythm, it must be consistent with the underlying logic of commercialization.

Back to the information and communication industry, it is actually very clear. Since the beginning of 2000, the 3G era has come, and at that time we had mobile Internet. In the last decade, the 4G era came, and we have the current digital economy era. So what is this decade? We see China’s 5G and the United States’ Starlink. The information and communication industry will definitely be able to achieve full coverage from 5G to 6G, meeting all our human travel requirements from the surface to low altitude and then to space. Of course, I think 8G should be the era of interstellar immigration. We will have network signals all the way from here to Mars, and it will become a reality.

Moderator: Capital participation requires a valuation and calculation. Can you give us a calculation for the field you are engaged in? How much money do you think it will cost based on the future development potential and the technology we have invested in?

Wang Yang: We have invested billions in research and development in the past six years. In our industry, whether it is a rocket company, a satellite company, or now a more advanced constellation networking company, its valuation will definitely exceed 10 billion.

Host: Regarding policies, what kind of policy soil is needed to plan for future industries?

Wang Yang: Considering the characteristics of low-orbit communication constellations in commercial aerospace, I think we should encourage the globalization of China’s commercial aerospace in the foreign trade sector, that is, the “going global” of the entire technology products and services. We look forward to the introduction of some national standards in this regard. We used to study some Western industry-university-research behaviors. In China’s system, from districts, cities, provinces to the country, the entire industrial policy support and innovation encouragement for each industry are very complete, but in fact, the real technology will eventually fall on commercial realization. This should be the government holding the baton, and then through the market economy, that is, the role of leading enterprises, to drive the innovation of engineering and original technology. This is actually a logical cycle. If we only mention one end, this matter will definitely be biased.

Host: What will our lives be like when this field develops to a mature stage?

Wang Yang: Let me make a creative summary. I believe that humans will always have the need to communicate with the outside world in the social system, so the implementation of all technologies and engineering around human communication will continue to develop iteratively. Like what we are doing in aerospace now, no matter where humans are now or where humans will explore in the future, we will ensure that there is network connection and communication methods. This is my wish.
