satellite industry rising star in it city
Shenzhen's satellite industry is drawn from a piece of white paper.
In 2007, China Aerospace Hi-Tech Holding Group Co.Ltd(000901) group carried out strategic cooperation with Shenzhen municipal government to establish an aerospace base in Shenzhen. Shenzhen Aerospace Dongfanghong Satellite Co., Ltd. (hereinafter referred to as Shenzhen Dongfanghong) established one year later is the first satellite enterprise in Shenzhen, opening the prelude to the development of Shenzhen's satellite industry.
At the end of 2011, test satellite 4, the first satellite developed by Shenzhen Dongfanghong, left the factory on time and successfully took off and passed the in orbit test.
Then, the world's first pulsar experimental satellite, China's first mass-produced microsatellite constellation, Shenzhen's first export international satellite, China's first polar exploration and remote sensing satellite... These first in a series of flights witnessed Shenzhen Dongfanghong's efforts in the development of China's microsatellites.
As of the press time, Shenzhen Dongfanghong has successfully developed and launched 20 micro satellites of different types, with a mass ranging from a few kilograms to hundreds of kilograms, covering the directions of technical test, communication, navigation, remote sensing and atmospheric detection. It ranks at the leading level in China in the overall design of micro satellites, integrated integrated electronic systems and other technical research.
Why can Shenzhen, which lacks major national aerospace projects and resource layout, rise rapidly and become an important town of satellite industry?
Hu Gefeng, chairman of Shenzhen Dongfanghong company, believes that the development of satellite industry in Shenzhen has the advantage of "favorable time, place and people".
First, the demand side is vigorous and the supply side is getting better. Shenzhen is one of the fastest growing cities in China. Urban construction is changing with each passing day. Traditional technical means have been fully applied in ecological environment, natural resources, urban management and urban safety. To continue to solve problems with high efficiency and efficiency, satellites can give full play to their special advantages. At the same time, the Internet, finance, communication, ocean, geographic information and other industries in Shenzhen are developing rapidly, and there is a large demand for satellite remote sensing, satellite communication, satellite navigation and so on. With the rapid development of commercial aerospace technology, it is possible to provide services with cost-effective solutions. The two-way effect of demand side and supply side has created a good environment for the development of satellite industry in Shenzhen.
The second is geographical advantage. Shenzhen has a good industrial foundation and has cultivated developed manufacturing clusters. Local microelectronics, machining, intelligent manufacturing, communication, geographic information and other industries are important ecological elements of commercial satellite industry. Under the traction of professional satellite enterprises, it is conducive to quickly form a satellite industry chain with complete elements and strong competitiveness. Shenzhen has entered the golden development period driven by the "double zones" of Guangdong, Hong Kong and Macao Dawan district and Shenzhen first demonstration zone, and the superposition of the "double zones" of Shenzhen Special Economic Zone and Shenzhen first demonstration zone. The development of satellite industry in Shenzhen is conducive to creating an international business card of Shenzhen and helping the construction of Shenzhen first demonstration zone.
In addition, it is Renhe. Shenzhen has built a strong innovation and entrepreneurship atmosphere, a good business financing environment and a strong willingness to cooperate upstream and downstream of the satellite industry chain, which is conducive to the rapid development of the satellite industry.
At present, Shenzhen has formed a relatively complete industrial system including satellite manufacturing, operation, key parts (chips) and satellite application. For example, Shenzhen Dongfanghong is in the field of satellite development, Asia Pacific satellite communication is in the field of satellite construction and operation, and key parts are Huada Beidou, Huaxin antenna and Hangsheng electronics. The industrial scale and overall competitiveness rank among the leading levels in China. In addition, it also gathered scientific research institutions such as the Institute of space science and applied technology of Harbin University of Technology (Shenzhen), the school of Aeronautics and Astronautics of Sun Yat sen University, the Shenzhen Institute of advanced technology of the Chinese Academy of Sciences (Shenzhen Beidou Applied Technology Research Institute), the national key Laboratory of surveying, mapping and remote sensing information engineering of Wuhan University and so on.
"Shenzhen's well-developed electronic information industry and manufacturing foundation provide strong support for the development of key parts for satellites and the R & D and production of various satellite application terminal products. Shenzhen has leading advantages and technology accumulation in artificial intelligence, big data development, communication technology and Internet of things system integration, so as to promote the development and application of satellite data products and services. In addition to resources, environment Ecological protection, disaster prevention and mitigation, emergency response, urban management and other scenarios. In the field of smart ocean, Shenzhen is strengthening the construction of a global marine central city, focusing on the development of marine economy such as marine electronics, marine engineering equipment, marine transportation and marine organisms, and also providing a wide industrial application space for satellite applications. " Zhang Yiping, President of Shenzhen Satellite Internet of things industry association, said.
prototype of cluster development
Despite various deficiencies, Shenzhen has made forward-looking industrial planning and layout, and listed the aerospace industry as one of the key future industries. As early as 2013, Shenzhen prepared the development plan of aerospace industry, proposed the development of avionics, UAV, satellite navigation applications, micro satellites and other industrial fields, and issued a number of policies to support industrial development. From 2014 to 2020, Shenzhen finance has arranged a total of 7 billion yuan to support future industrial development for seven consecutive years, including aerospace industry.
The advance planning in policy and the mutual support in industry have made the satellite industry in Shenzhen grow from scratch and the industrial context continues to extend. From the initial emergence of Shenzhen Dongfanghong, the cluster development trend of Shenzhen satellite industry has become increasingly prominent.
Asia Pacific satellite broadband communication (Shenzhen) Co., Ltd., established in 2016, is committed to building a global coverage, safe and reliable broadband satellite communication system integrating heaven and earth and building an internationally competitive "satellite +" industrial cluster.
The Asia Pacific 6D satellite (named "Shenzhen satellite") launched in July 2020 is the first high-throughput satellite customized for mobile carrier communication in the world, making Shenzhen the only city in China with Ku band high-throughput satellite and the second city with synchronous orbit satellite.
As a civil and commercial communication satellite with the largest communication capacity, the largest beam, the largest output power and the most complex design degree in China, the communication capacity of Asia Pacific 6D satellite reaches 50Gbps, dozens of times that of traditional satellites. At present, there are more than 10000 carriers (terminal stations) such as network access aircraft, ships, emergency communication vehicles and portable stations, ensuring the landing of chang'e-5 returner of China Central Television Shenzhou 12 launch and return module landing, Henan flood rescue and other major projects and key tasks.
In addition to satellite development, satellite industry applications represented by communication, navigation and remote sensing are also the focus of the industry. It makes satellite technology in the vast space within reach.
It is understood that the satellite navigation and location service industry alone includes the development, production and sales of basic products such as upstream basic devices, basic software and basic data; Midstream includes the development, production and sales of various terminal integration products and system integration products; Downstream is the application and operation service link based on various technologies and products.
At present, relying on the advantages of information technology, Shenzhen ranks first in the industrial scale and number of enterprises in the field of R & D and production of complete satellite navigation terminals in China. It has a relatively complete industrial chain covering product R & D, production and manufacturing, system integration and operation services. The civil vehicle mounted satellite navigator produced and manufactured in Shenzhen accounts for more than 40% of the national market share.
Huada Beidou, which settled in Longgang in 2016, focused on the chip level core technology of Beidou satellite navigation, accelerated the development and industrialization of key devices such as advanced Beidou satellite navigation chips and modules, and vigorously promoted the application expansion and popularization of chip level application solutions. The overall technical indicators of many of its products have reached the leading level in China.
On January 6, the reporter learned from Huada Beidou that since the world's first multi system multi frequency baseband RF integrated high-precision chip supporting Beidou No. 3 signal system was independently designed and developed in 2017, the company's cumulative shipment of chip products has exceeded 20 million, which has been widely used in various application markets. Among them, in the field of mass consumer applications, Huada Beidou has become the only chip supplier for Qingju, meituan, hello and other bike sharing manufacturers in the new generation of high-precision positioning bike sharing applications. In terms of smart phones, Huada Beidou and Lenovo Group jointly developed and mass produced the world's first "dual band Beidou high-precision positioning mobile phone" based on the self-developed dual band multi system SOC chip, realizing the mass production and application of the world's first domestic Beidou dual band ultra-precision positioning smart phone. This is the first time that domestic Beidou dual band positioning chip has been widely used in the field of smart phones.
"With the development of mobile communication technology and the rapid rise of the Internet of things industry, there will be more and more application scenarios based on high-precision positioning. After mobile phones take the lead in supporting dual band Beidou ultra-precision positioning, all industries, Internet of things terminals and applications will also usher in new changes and rapid development. Based on Beidou high-precision positioning technology, terminals have meter level and sub meter level positioning capabilities After the application of location-based data can achieve further functional upgrading, so that personal mobile Internet applications such as mobile navigation, tourism services and game interaction, as well as on-board devices, wearable devices, logistics tracking, road facilities, and even UAVs and driverless can achieve accurate positioning in future industry applications. The high-precision location service around positioning will also become an inevitable trend for the development of smart phones and smart IOT applications in the future. " Sun Zhongliang, general manager of Shenzhen Huada Beidou Technology Co., Ltd., said.
The CIMC LEO satellite IOT Industrial Park in Guangming District, relying on the China International Marine Containers (Group) Co.Ltd(000039) industrial chain ecology, has gathered a number of core innovation elements upstream and downstream of the satellite IOT industrial chain. The office address of Shenzhen satellite IOT Industry Association is located in the park.
Zhang Yiping told reporters that in October 2020, CIMC industrial city, together with nearly 100 units such as aerospace Dongfanghong, Hwa Create Corporation(300045) , star link Tiantong, Huaxin antenna and aerospace Huatuo, jointly initiated the establishment of Shenzhen Satellite Internet of things industry association. At the same time, it complied with the national strategic plan for the construction of aerospace information infrastructure, focused on the application and industrialization of satellite communication and remote technology, and accurately linked the government Universities, scientific research institutions and core industrial resources have established the satellite Internet of things industry innovation research institute.

Last year, it also prepared a 2021 white paper on satellite and application industry and issued four group standards to assist in the implementation and deployment of policies, accurately link industrial resources and do a good job in the development of the industry‘ Connector 'and industry' accelerator '. " Zhang Yiping said.
policy timely rain to build a highland of satellite and application industry
With the in-depth promotion of "new infrastructure", the information infrastructure represented by 5g, Internet of things, industrial Internet and satellite Internet also ushered in an opportunity to stimulate the large-scale growth of satellite and application demand.
Entering the new era of satellite industry, Shenzhen should make new achievements.
In the 14th five year plan for Shenzhen's national economic and social development and the outline of the long-term goals for the year 2005, which was published in June 2021, it was mentioned that "key technology research should be carried out in the fields of space exploration, satellite navigation, satellite remote sensing, satellite communication and digital space". In the implementation of the future industry leading plan, "Participate in the development of the national deep space exploration and on orbit service and maintenance system for spacecraft, deepen the promotion and application of Beidou system, and support the development of high-throughput satellite broadband communication system". In building the world's leading digital infrastructure, It is proposed to "build a communication network infrastructure system covering '5g + gigabit optical network + smart private network + satellite network + Internet of things' to realize ubiquitous high-speed network connectivity".
In the same month, the Shenzhen Municipal Development and Reform Commission announced the Shenzhen Municipal opinions on supporting the development of satellite and application industry, from the demonstration of characteristic application scenarios, the development of major equipment and key parts, the R & D and application innovation of core technologies, the industrialization of core products and parts, the construction of civil space infrastructure Sixteen specific measures are proposed in six aspects of major industrial public service platforms to build a "satellite +" innovation ecosystem, promote the construction of aerospace information infrastructure and industrial development, and build Shenzhen into an innovation highland of global satellite and application industry.
The person in charge of Shenzhen R & D center, State Key Laboratory of surveying, mapping and remote sensing information engineering, Wuhan University, said that with the help of favorable policies, we will integrate satellite industry resources and establish a platform for the transformation and industrialization of technological achievements for satellite communication, navigation and remote sensing technologies.
