Today, the successful launch of “One Arrow and 26 Stars” has attracted many customers. Li Qinfeng said: “Now we already have many orders in line, and some have even ranked until the next year. At present, our customers are mainly domestic commercial satellites in China.Company and scientific research institutions.
Li Qinfeng said that in the field of commercial aerospace, the cost of carrying carrons per kilogram of goods is generally 50,000 to 100,000 yuan.The team currently developed Grand Transport, highly reliable, and low -cost liquid carrier rocket “Lie Arrow 2” has entered the stage of engineering development.Cost freight ships.
“Space Tourism will be a very good commercial aerospace project in the future. Ordinary people can come to space for sightseeing after exercising the relevant standards.” Li Qinfeng introduced that the Asian orbit aircraft can be equipped with 7 passengers in a single time, and the maximum flight height will be the height of the maximum flight height.When it comes to 100 to 120 kilometers, passengers can get a “astronaut” experience for about 10 minutes after simple professional training, including the weightless experience of getting rid of the gravity of the earth for about 3 minutes.
Low -altitude economy and car networking are dependent on commercial aerospace
Speaking of the future application of commercial aerospace, Professor Zhang Jinxiu, deputy dean of the Academy of Aerospace of Sun Yat -sen University, told reporters that in the future of the entire commercial aerospace industry chain, satellite manufacturing and launch services accountFor service applications, such as the driverless driving of the car, the low -altitude economy drone and the flying vehicle intelligent navigation and high -speed communication network.”In the future, as there are more and more satellites in the sky, and more importantly, make the back -end ground equipment and industrial applications.”
According to Zhang Jinxiu, low -orbit remote sensing satellites, especially synthetic aperture radar satellite constellations, can obtain massive remote sensing data, whether day and night, whether it is windy and rainy.Ultra -high -rise buildings every year’s settlement and deformation.At present, because the data is obtained in time and uneven, it is not yet possible to achieve effective monitoring. However, with the construction of the low -orbit satellite constellation, the digital monitoring of large -scale urban facilities based on satellite remote sensing data will be possible.In addition, massive remote sensing data can also be used in rural areas to monitor the planting rate, production conditions, and even pests of pests.
The application of commercial aerospace on the Internet and low -altitude economy is equally important.Geely Space puts the headquarters in Nansha, Guangzhou, and the company’s satellite “Geely Future Constellation” has continuously launched the sky in recent years.Zhang Jinxiu introduced, “Guangdong Highway Network is very dense, and it will be an important region for Internet applications in the future. The low -orbit satellite communication network will improve the driving safety and smart travel experience of the car, making the car a diversified life and intelligent services.The carrier is also supported by the low -altitude of the low -altitude aircraft such as the drone and the flight car.All are closely related to commercial space.
The low -orbit communication network of commercial aerospace also has a wide range of application prospects in Guangdong.Zhang Jinxiu introduced: “There are a large number of islands in Guangdong, long coastlines, between islands and islands, how can people and ships communicate after going out of the sea? In the past, the price of satellite communication was expensive, the signal was poor, and the delay was long. With commercial aerospace satellite communicationThe construction of the network uses the mobile phone to directly connect to the satellite network for communication, which has a very broad market value for Guangdong with coastal provinces.
Zhang Jinxiu told reporters that the college and many head -of -head companies of commercial aerospace have cooperation in industry -university -research. “This year is the centennial celebration of Sun Yat -sen University.The new technology experimental satellite or space medical micro -gravity experimental satellite designed and developed by the students themselves.”After the satellite goes to heaven, we will cooperate with some space micro -gravity experiments, involving space medicine, new material technology, etc. It is expected that we will implement such cooperation within the next six months to one year.”
Zhang Jinxiu introduced that the college currently has a good talent training ability on the full -chain of commercial aerospace.”At present, our 40%~ 50%of graduate students stay in Guangdong. With the landing of many commercial space companies, more people will stay in Guangdong to develop in the future. Many of us have entered the low -altitude economy development to develop flying cars to do flight cars.Research on the side. “
Guangzhou commercial aerospace is vigorous
Speaking of the development of the Guangzhou commercial aerospace industry chain, Li Qinfeng said that Guangzhou is very supportive of commercial aerospace and focuses on building Guangzhou Nansha into the “third pole” of commercial aerospace. Nansha District also introduced the “Guangzhou Nansha New District (Free Trade Area) at the end of last year last year last year.”Supporting Measures for Promoting the High -quality Development of the Commercial Space Industry”, which supports all aspects of the initial financing support of the enterprise and the aerospace device development subsidy. “In this regard, we feel very strong.important reason.”
Li Qinfeng said that the foundation of Guangzhou’s industrial chain is very strong. Whether it is advanced manufacturing, software, and even electronic chips, these foundations will play an important role in the continuous expansion of the commercial space industry chain.”The requirements of various aerospace equipment are very high, and the demand is not very large. Therefore, in the past, socialized enterprises were willing to get involved in this field.It will produce a large number of traction and leading the entire market, and it will also drive companies in Guangzhou and even the entire Greater Bay Area to join the commercial space industry. “
Zhang Xiaohu, a professor at the School of Aerospace University of Sun Yat -sen University, believes that in the field of commercial aerospace, Guangzhou has been involved in enterprises from space applications to carrier tools. The company is the supporting capabilities of the Greater Bay Area in terms of electronics and materials, as well as huge market demand.Whether it is the development, launch of satellites, or even future space tours, there is a lot of development imagination.Traditional aerospace is complementary to commercial aerospace, and commercial aerospace is stronger in terms of cost control and market response capabilities.”From the perspective of the supply chain, the manufacturing capacity and supporting capabilities of the Greater Bay Area are very important for commercial aerospace companies to reduce costs and improve the popularity of commercial aerospace.”
Zhang Jinxiu also believes that the development potential of commercial aerospace in Guangzhou is huge, and the industrial chain has gradually improved. From satellite manufacturing to launch services, to ground equipment and industrial applications, Guangzhou is gradually forming a closed -loop ecosystem of commercial aerospace.
