In April 23rd, the first China spaceflight conference held in Harbin, Chinas famous spaceflight project zero - weight space combined with Shenzhen listed enterprises Hua - Xin ark, jointly launched the Ling magpie remote sensing Constellation program. The magpie constellation plans to launch 132 optical satellites at the beginning of the project to achieve half a day watching the earth. Remote sensing satellites, also known as earth observation satellites, are one of the three major areas of satellite application. The earth observation satellites take pictures of the earths surface, and the image data obtained are widely used in various civil fields. Due to the characteristics of satellite orbit operation, to cover more areas, enough satellite networks are needed for taking pictures. The pigeon constellation of the PlanetLabs is currently the largest constellation of earth imaging satellites in the world, with about 350 satellites. Today, China will also have its own magpie. Chinas private space enterprises have put forward their own satellite networking plan to achieve half a day covering the earth. 132 satellite networking Lan Lidong, chairman of the zero gravity laboratory, introduced in Harbin that the initial plan of the psionic constellation is made up of 132 6U cubic stars with an optical resolution superior to 4 meters and running at 500 km high in SSO and LEO. After the constellation deployment is completed, a high time resolution to earth observation capability will be formed to cover 12 hours of global coverage and a 30 minute revisit to the key areas. Zhangbei, the general manager of the zero gravity laboratory, revealed that the test star of the psionic constellation (double star) is scheduled to launch within the year, and the first batch of business satellites can launch an arrow and ten stars in the next two years and the next two to three years will complete the first phase of the constellation network. At that time, the data products obtained by psionic magpie can be used in many fields, such as agricultural monitoring, disaster prevention and disaster reduction, urban comprehensive management, river basin control and so on. Meanwhile, the magpie constellation will be able to see the whole earth in half a day, and live the earth will also become possible. The long-term planning of the constellation will increase the number of satellites to 378, which will realize the quasi real-time observation effect of 10 minutes revisit in hot spots, so that the obtained data will be better used and easier to use to meet the needs of various kinds of remote sensing data service. Compared with the homogeneous distribution of the pigeon constellations of the American Planetary Laboratory (PlanetLabs) of the international constellation system, the magpie designed a formation flight mode with five satellites as a cluster of stars, which can complete a variety of imaging modes such as broad splicing imaging and stereoscopic imaging at a certain point of the earth, thus forming a more abundant form. The rich data product type. Construction of satellite production line The zero gravity laboratory is closely related to the two companies of Hua Xun ark. In February 2018, the zero gravity laboratory announced the completion of 20 million RMB A round financing. The investment side was the Hua News ark. The capital will be mainly used to build the cubic star manufacturing plant in Shenzhen and expand the team size. It is understood that building a cubic star manufacturing plant in Shenzhen is designed to avoid the long cycle of traditional satellite production and high cost, and to solve the short board with large and inadequate capacity of the domestic constellations. The factory has initially designed and implemented 50 sets of cubic star and component production capacity per year. Zhangbei said that the factory could meet the production needs of the magpie constellation, and the constellations were deployed in accordance with the planned launch, and the surplus capacity could also serve the relevant domestic institutions and enterprises. In addition, mass production capacity and self built production lines are conducive to further reducing constellation construction costs and achieving rapid product upgrading. This is also the main experience of international commercial aerospace enterprises. At present, the US star space enterprise OneWeb, which is the main satellite network, plans to establish a standardized satellite production line with Airbus. In the field of rocket manufacturing, two famous rocket start-ups in China have built their own production lines in Huzhou and Chongqing new areas in Chongqing, respectively. Like the combination of OneWeb and Airbus, the magpie constellation is mainly invested and operated by Hua Xun ark group. Zhangbei said that as a co sponsor, Hua Fang boat group and zero gravity laboratory have agreed with the Tsinghua University, the Beihang University, the PLA Aerospace Engineering University, the space science and technology group, the space science and technology group, the Chinese Academy of Sciences, the CAS, the sky chain measurement and control, and other universities and enterprises, in operation and global measurement and control. Deep cooperation with data reception, data transmission and preprocessing. In the field of launch services, in addition to the choice of mature commercial rockets such as long march eleven, the magpie constellation will also try to cooperate with a number of private rocket companies. Manufacturing and launching satellites are only the previous work. As a global constellation, data reception and transmission after network operation, and the analysis of massive remote sensing data are the most important things to ensure the commercial operation of the constellations. He said. The production line is located in Shenzhen, reflecting the economic geography of domestic commercial space to a considerable extent. At present, there are about 60 Commercial Space start-ups in China, most of which are concentrated in Beijing, which is the traditional R & D center of the space national team. And similar to Shanghai, Xian and other traditional space city, there are also corporate layout headquarters or R & D base. Shenzhen reflects the strength of the electronic manufacturing industry in the Pearl River Delta, which will provide an electronic component supply chain for the manufacture of satellites and rockets. Zhejiang and Huzhou, and Chongqing, which are the two start-ups, are all important manufacturing bases in China. Commercial space is booming this year, which is known as the first year of the industry. The 2017 Satellite Industry Report of the American Satellite Industry Association (SIA) pointed out that the global output value of the earth observation industry in 2016 was 2 billion dollars, although it was less than 1.6% of the total output value of the entire satellite application industry, but increased by 11% over the same period, leading the vast majority of economic areas. People in the industry pointed out that real-time, near real-time remote sensing applications, coupled with powerful data processing and analysis capabilities, will make the economic indicators of remote sensing applications show an explosive growth trend, attracting more participants and larger investment.
