The sky is sharp and the sky is powerful.” In the military parade to commemorate the 70th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War, the second party of conventional missiles participating in the military parade was formed by a brigade of the Second Artillery Corps. 21D conventional missile. This missile has the characteristics of fast response speed, tracking and tracking standards, and high strike accuracy. It can accurately strike large and medium-sized moving targets at sea, achieving a new leap in the ability of the Chinese military to strike with conventional missiles.

"The accuracy of missiles depends mainly on navigation." In recent years, with the continuous development of my country's military equipment, navigation technology has been at the forefront of the world.

"The application of global satellite navigation systems is only restricted by human imagination," a scientist once said. The satellite navigation system is an important space information infrastructure of a country, and an important symbol and concentrated expression of the country's comprehensive national strength, core competitiveness, and scientific and technological innovation capabilities. Especially in modernization and information warfare, the role of navigation has become more and more prominent, so all countries attach great importance to the development of the navigation industry.

At present, my country attaches great importance to the development of the satellite navigation industry. The National Development and Reform Commission took the lead in jointly drafting the Beidou industry mid- and long-term plan with multiple departments, and included the Beidou navigation system in the "National Medium and Long-term Science and Technology Development Plan Outline" 16 major science and technology projects one. According to the prediction of the China Satellite Navigation and Positioning Association, the output value of China's satellite navigation and location service industry will exceed 225 billion yuan in 2015; by 2020, China will build a Beidou satellite navigation and positioning system that serves the world. By then, users of China's satellite navigation and location industry The scale will become the world's largest, and the annual output value of the industry will exceed 400 billion yuan.

Showcase in the military field

China's BeiDou Navigation Satellite System (BDS) is a global satellite navigation system developed by China. It is the third mature satellite navigation system after the United States Global Positioning System (GPS) and the Russian GLONASS satellite navigation system (GLONASS). Because the missiles and other precision strike and positioning weapons of many countries in the world currently require military satellites for precise guidance. The success of Beidou can get rid of China's dependence on the US GPS and avoid being affected by US navigation satellites at critical moments.

Prior to this, the General Staff of the People's Liberation Army organized a Beidou satellite navigation operation application exercise in northern Guangxi, and simultaneously demonstrated the results of Beidou's systematic application. After years of application and practice, the Beidou system has initially formed a systematic, actual combat, and normalized application capability.

This exercise focused on improving the effectiveness of Beidou satellite navigation applications, and built a Beidou application system featuring multi-source information fusion, flat networking command, multi-platform integrated application, and hierarchical management support. It comprehensively uses precise positioning and navigation, unified time-space reference, and real-time position. Reporting, remote information transmission, battlefield situation sharing and other functions have realized the scientific decision-making and command of the troops, rapid maneuver deployment, real-time and efficient coordination, precise firepower strikes, precise after-installation support, and provided a model and technical reference for the military's Beidou combat application .

A well-known military expert and military commentator Song Zhongping pointed out that as China's weapons and equipment, including our country's military development, it has gone to the open seas and oceans, and will strengthen our military presence globally in the future. Therefore, Beidou navigation satellites must have global navigation capabilities. From the perspective of military use, the Beidou system has four main functions: navigation, positioning, timing, and communication. These four major functions will play a great role in military weapons, including the operation of the system.

Professor Li Guangxia, a satellite communications expert from the Chinese Institute of Command and Control, said that China’s Beidou satellite navigation system is comparable to GPS, which is not an exaggeration. It is estimated that by 2020, my country will build a global satellite navigation system consisting of 5 geostationary orbit and 30 geostationary orbit satellites, which will provide services to the world.

"At present, many of my country's active military equipment still uses GPS, but the Beidou navigation system should be used in the research equipment. And as the Beidou navigation gradually matures, it will greatly enhance the deterrence of our military’s missiles. , To provide the prerequisites for the troops to win modernized and informatized wars." A staff member of the Air Force Missile Academy of the Chinese People's Liberation Army who did not want to be named told the Qianzhan Industry Research Institute.

"Beidou Navigation is an autonomous and controllable system in our country, and the application of the military is the first to bear the brunt. Without such a technology as a positioning system, it is obviously very difficult for the military to catch up with developed countries in Europe and America in terms of military strength and military informatization. Yes. The military’s demand for positioning system applications is relatively large, which will also drive the rapid development of my country’s navigation industry.” Li Donghang, director of the China Satellite Navigation and Positioning Association Consulting Center, told Qianzhan Industry Research Institute.

The civilian field is blooming everywhere

Previously, the Ministry of Industry and Information Technology issued the 2015 Special Action Implementation Plan for the Deep Development of Military-Civil Integration, and launched the 2015 Special Action for Deep Development of Military-civilian Integration. According to the special action, the Ministry of Industry and Information Technology will prepare and issue the "Catalogs" of "Military-to-civilian" and "Civilian-to-military" this year. At the same time, it will increase financial support for "Military-to-civilian" and "civilian-to-military" projects, and the development of integrated military and civilian industries. More social funds enter the field of military-civilian integration development, and better coordinate military and civilian construction.

Recently, China Location "Qianxun Location Network Co., Ltd.", jointly funded by Alibaba Group and China North Industries Group, was officially established in Yangpu District, Shanghai. This marks the beginning of the application of China's own Beidou satellite navigation system. Important steps are also an in-depth development of the Beidou system's "military-to-civilian" development. With the concept of "Internet + Location (Beidou)", the company builds a location service cloud platform through the integration and construction of a network on the basis of Beidou to meet the needs of the country, industry, and the mass market for precise location services.

Li Donghang pointed out that China has entered the "Beidou+" era. The development of "Beidou+" can give birth to new economic forms, build a new industrial chain and provide an environment for public entrepreneurship and innovation. After the top-level military-civilian integration has been upgraded to a national strategy, whether it is policy support or actual advancement, the deep military-civilian integration is accelerating. Beidou navigation industry, as the connection point of communications, electronics and transportation industries, will connect supporting enterprises in various links through industrial linkage to promote the rapid and healthy development of the industry.

"In this military parade, some high-tech methods such as Beidou satellite navigation and positioning system, laser rangefinder, isokinetic timing system, digital tachometer, etc. were applied to the training, which greatly improved the training efficiency. It can also be seen from this. The maturity and progress of my country’s navigation industry. Beidou navigation has a wide range of applications in transportation, telecommunications, electricity, land resources, surveying and mapping geographic information, weather forecasting, marine fisheries, public safety, disaster relief and location services, and has a huge market ". Xu Xing from the Navigation Products Division of Beijing Beidouxingtong Navigation Technology Co., Ltd. told Qianzhan Industry Research Institute.

For example, if Beidou navigation can be popularized on civil vehicles in our country, in the future, vehicle driving information can be collected in a unified manner. After data processing and analysis, urban traffic congestion and parking difficulties can be solved. The most important thing is to achieve these foundations. Autonomy and control of information.

Industry insiders pointed out that Beidou navigation cannot be understood only as high-level projects such as aviation, satellite, and military. There is still much to be done in civil use. The "mobile" nature of the mobile Internet makes information interaction not restricted by space. Combining location information with various user needs can expand new market space and generate new value.

And with the maturity and cost reduction of domestic sensor products, it can be used and connected on a large scale and high-density on smart terminals. Beidou-based location services and cloud computing, Internet of Things, Internet, satellite Internet, and big data, etc. Cross-border integration and integrated applications in the field have become an inevitable trend, and the Beidou system will gradually become an indispensable supporting resource.
