Successfully launch China successfully launched the Geely Constellation 03 satellites Satellite Successfully into its pre-determined orbit…
This mission is the 534th flight of the Long March series of carrier rockets. As the first liquid carrier rocket in China to adopt the “three-level” test and launch mode, the Long March 6 insists on improving and optimizing on the basis of the existing first set of overall transportation and erection systems. This mission uses the newly developed second set of overall transportation and erection systems for the first time. While improving the convenience of operation and environmental adaptability, redundant design and testability design are added to key links to shorten the docking, erection and landing time by 2/3, effectively improving the work efficiency of the launch site.
The third orbital satellite of Geely’s Future Mobility Constellation was successfully launched at the Taiyuan Satellite Launch Center with 10 satellites in one launch. Currently, 30 satellites of Geely’s Future Mobility Constellation are in orbit….
The Long March 6 is a small liquid carrier rocket with a three-stage tandem configuration. The first and second stages use liquid oxygen/kerosene engines, and the third stage uses nitrogen tetroxide/undimethylhydrazine propellants. The rocket is 29.932 meters high, with a first-stage diameter of 3.35 meters, and second and third-stage diameters of 2.25 meters. It can be equipped with 2.6-meter and 2.9-meter diameter fairings. The takeoff mass is about 102 tons, and the takeoff thrust is 122 tons. Its low-Earth orbit (LEO) capacity is greater than 1.5 tons, and the 700-kilometer circular sun-synchronous orbit (SSO) capacity is 1 ton.
The Long March 6 is the first flight model of China’s new generation of Long March carrier rockets. On September 20, 2015, the Long March 6 (Yao-1) carrier rocket successfully completed its maiden flight at the Taiyuan Launch Center, marking the entry of the new generation of Long March carrier rockets into China’s aerospace arena.
The birth of the “Long March 6” is of groundbreaking significance. Its first stage is equipped with a YF-100 liquid oxygen-kerosene engine, and its second stage is equipped with a YF-115 liquid oxygen-kerosene engine. These are the main power configurations of the new generation of “Long March” rockets. The first flight of the “Long March 6” is also the first flight of these engines. At the same time, the “Long March 6” has also created many international firsts. For the first time in the world, the self-generated supercharging technology of the oxygen tank of the high-pressure regenerative liquid oxygen-kerosene engine was proposed, which solved the internal supercharging of the engine oxygen tank; for the first time in the world, the high-power servo mechanism control technology of direct drainage of high-pressure kerosene was proposed, which solved the problem of large center of mass deflection of the engine; for the first time in the world, the 200K (200 degrees Celsius) large temperature difference foam sandwich common bottom tank technology was proposed, which solved the effective insulation and load-bearing of the liquid oxygen-kerosene propellant tank.
This launch mission is the 12th launch mission of the Long March 6 carrier rocket, the 217th launch of the Long March series of carrier rockets developed by Shanghai Aerospace, and the 534th launch of China’s Long March series of carrier rockets.

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.

Wang Yang, CEO of Space-Time Daoyu: From the perspective of system engineering, positively define satellite communication and navigation solutions
The world’s fastest mass-produced satellite Internet passenger car – Jikrypton 001 FR was released. Click on the video to witness that Space time Daoyu and Jikrypton are the first to implement vehicle-mounted satellite communication functions, providing two-way satellite messaging and satellite call services.
On September 1st 2023 , Jikr and Space-time Daoyu jointly released the world’s fastest mass-produced satellite Internet passenger car . On the Jikrypton 001 FR, which is about to be mass-produced and delivered, it is the first to mass-produce and realize the vehicle-mounted satellite communication function, providing two-way satellite message and satellite call services. At the same time, Spacetime Daoyu launched the world’s first satellite Internet vehicle-mounted integrated glass antenna and a high-throughput satellite Internet terminal with “vehicle-end” integrated design. In the future, car users can access the satellite network anytime and anywhere, and have a new travel experience.
The following is the full text of Wang Yang, the CEO and chief system engineering expert of Spacetime Daoyu, when he was interviewed by the media at the Krypton Evolution Day press conference:
As a luxury technology brand in the new era, Jikrypton focuses on the research and development of forward-looking technologies for smart electric travel. This time, it has achieved mass production of satellite communication technology for the first time in the world , which fully proves the continuous evolution of the Jikrypton brand. Spacetime Daoyu and Jikryon continue to carry out in-depth cooperation, based on the core capabilities of the future travel constellation, integrating the core technologies of the commercial aerospace and intelligent pure electric vehicle industries to create industry-leading satellite Internet car experience solutions.
The rapid and large-scale application of space-time Daoyu and Jikrypton’s in-vehicle satellite communication services has benefited from Geely Holding Group’s 30 years of development in the automotive industry and its continuous investment in the high-tech field in the past 10 years .
Spacetime Daoyu joined 3GPP, China Communications Standards Association (CCSA) and other standardization organizations in 2018 to conduct in-depth research on 5G+ satellite communication technology and standard formulation. In the Aerospace Communication Technology Working Group of the China Communications Standards Association (CCSA TC12), he took the lead in establishing the project “Research on Key Technologies and Applications of Vehicle Satellite Communication Systems” and participated in a number of CCSA related research projects and standard formulation. Participate in the 3GPP RAN working group to jointly promote the application of LTE and 5G NR communication systems to V2X related research topics and standard formulation. The future R19 version will also continue to actively participate. At the same time, United Jikr completed the “General Specifications for Satellite Communication Vehicle Terminals” standard project at the China Society of Automotive Engineers (CSAE). Together with terminal manufacturers, the Telecommunications Terminal Industry Association (TAF) completed the draft of the standard “Technical Requirements and Test Methods for Consumer Terminals Supporting Low-Earth Satellites”.
In 2021, Spacetime Daoyu has completed the development of multiple vehicle-mounted satellite Internet system terminals and satisfied multiple scenario tests. At the beginning of 2022, Jikrypton and the Space-Time Daoyu team decided to introduce in-vehicle satellite Internet services into mass-produced models. This requires overcoming two major problems: First, this is the first time that aerospace products have been developed and put into production at the automotive level . From product design, software and hardware architecture, component selection and even practicality in multiple environments, all must be satisfied with the vehicle level. Regulatory standards. Second, the implementation paths of satellite communication functions in cars and mobile phones are different. The differences between the automotive field and the consumer electronics field determine the differences in technology evolution routes. Before product release, Spacetime Daoyu has completed testing of all scenarios in more than 20 provinces and cities.
Space-Time Daoyu revolves around the evolution of various models of Jikrypton in the future, and defines satellite communication and navigation solutions positively from the perspective of system engineering.
In addition to the current two-way satellite messaging and satellite calling functions, more cutting-edge satellite glass antenna technology and satellite Internet functions provided by high-throughput flat-panel antennas have entered the actual testing stage. These core technologies and products will be part of Ji Krypton’s continued evolution. In the era of 6G space-ground integration, whether traveling on land, ocean, or at low altitude, human beings’ communication needs will definitely be met. Time and Space Daoyu has made systematic preparations, using forward engineering definition rather than reverse engineering innovation.
Jikrypton 001 FR with on-board satellite communication function is the most important intelligent terminal of Geely system. It is actually the carrier of our travel mode.
In the past 30 years, every technological iteration in the information and communication industry has brought about changes in lifestyles. But in fact, from 2G, 3G, 4G to the current 5G, about 70% of the space on our planet is still not covered by ground network signals. In the continuous iteration of the information and communication industry from 5G to 6G, the integration of space and earth brings more imagination space to intelligent network connection and autonomous driving.
Through the deep integration of aerospace technology and new energy technology, Space-time Daoyu continues to promote the integrated application of communication, navigation, and remote sensing technologies in the travel ecology, empowering autonomous driving and intelligent networking, and providing high-reliability, high-security, and cost-effective Satellite application products and services enable the highly coordinated development of the commercial aerospace industry and the intelligent pure electric vehicle industry.
