Beidou navigation has encountered application bottlenecks. Shen Xuemin, deputy general manager of Beidou Navigation, believes that it is not technology, but the US GPS market share is too high. "The problem of Beidou is not that there is no application market, but the terminal, chip, and industry support are not supported. The application threshold is high, and the application market is not stimulated." Another person in charge of Beidou said.
The US GPS only provides meter-level positioning services, and the high-precision positioning service is considered by the industry to be the starting point for China Beidou Navigation to achieve the curve overtaking GPS. It is reported that the next three years will be an important window for Beidou, and if it is missed, it will be quite passive.
The State Council executive meeting recently passed the "13th Five-Year National Informationization Plan", which proposed 12 priority actions for the construction and application of the Beidou system.
Beidou Navigation is a major national science and technology project. In 2015, the new generation of Beidou navigation satellites realized the establishment of inter-satellite links, indicating that Beidou navigation not only reaches the international advanced level, but also has the ability to deploy to the world. Shen Xuemin, deputy chief of the Beidou satellite navigation system, said that it is hoped that Beidou can promote its application, because the development of the Beidou system can be a virtuous circle.
The more users, the lower the cost and the stronger the competitiveness. Application progress has become a key factor in the success of Beidou navigation commercialization.
Mature technology and gyro-type industrial chain
The Beidou satellite navigation system is a self-developed, independently operated global satellite navigation system being implemented in China.
In 1994, China launched the construction of the test system for the Beidou satellite navigation project. In 2011, Beidou Navigation was included in one of the 16 major national science and technology projects. In 2012, Beidou Navigation was officially launched to provide services to the Asia Pacific region. In March 2015, China successfully launched the first new generation, namely the Beidou three-generation navigation satellite; from July to August, China successfully launched the 18th and 19th satellites of Beidou navigation, and the two satellites realized the establishment of inter-satellite links. It marks that China has successfully verified the core technology of the autonomous operation of the global navigation satellite constellation, and provided the basis for the Beidou satellite navigation system to expand from the Asia-Pacific region to the global construction.
In an interview with reporters, Shen Xuemin said that China's Beidou satellite technology is mature, and it has achieved complete localization and production batchization. In addition, China's rocket launches "one arrow and many stars" competitiveness, Beidou satellite has a cost-effective advantage, and then it is necessary to quickly whip. development of. In the next five years, the number of Beidou satellite launches will be two or three from the previous year, and accelerate to five or six shots per year.
"The task is very tight and very nervous." Shen Xuemin said.
China Beidou Navigation has been recognized by the United Nations as the core supplier of the four major satellite navigation systems in the world together with US GPS, Russian GLONASS and European GALILEO. Among the four navigation systems, the US GPS is currently the most mature satellite navigation system with the most mature system. After the US GPS went to the mass application, it became a new IT growth point after telecom and the Internet. The data shows that the global GPS market share of the United States exceeds 90%.
With the US GPS, why should we develop China's Beidou navigation? In addition to information security, Beidou navigation features more, such as the addition of communication (texting). For example, Shen Xuemin said that the Mekong River tragedy is well known. If Beidou navigation is applied, the Chinese merchant ship is hijacked in the Golden Triangle. Through the Beidou terminal, it can communicate with the back office. The backstage of the control ship knows where the ship is and can rescue it.
Cui Yinqiu, deputy director of Beidou Office of China Communications Construction Co., Ltd., also deeply understands that Beidou Navigation has played an important role in offshore operations and land tunnel construction projects.
"After the technological breakthrough of Beidou navigation satellite manufacturing, it is hoped that Beidou can promote the application, because the Beidou system development can be a virtuous circle." Shen Xuemin said.
According to reports, the current US satellite navigation industry chain is pyramid-shaped, and the downstream application output value accounts for more than 70% of the entire industrial chain. In contrast, China's Beidou industrial chain is gyro-type, with downstream production output accounting for less than 30%. The downstream business returns are small, and the government alone has long-term investment, and the future is difficult to sustain.
"Without application, there is no support." A Beidou people believe.
According to public information, a number of listed companies have entered the Beidou basic products and terminal products, such as Haige Communication, Zhenxin Technology, Beidouxingtong, Oubit, Hezhong Shuangzhuang, Zhonghaida, and Huali Chuangtong.
Application bottleneck under GPS rolling
The satellite navigation system includes three parts: sky, ground and terminal applications.
In 2012, when Beidou Navigation provided navigation, positioning, timing and short message communication services to the Asia Pacific region, it promised to provide free services with an accuracy of 5-10 meters. This positioning accuracy is comparable to that of the US GPS. But some companies have found that meter-level accuracy is not enough.
In 2014, Ali acquired the Gaode map. After relying on the GPS map of the US GPS in the logistics, network car, unmanned field, Ali found that the positioning accuracy is not enough. At this point, they encountered the China Ordnance Industry Group, which is building a ground-based augmentation system. The latter is thinking hard about how the ground-based augmentation system software is done and where the application market is. The two sides hit it off. In August 2015, each of them invested half of the establishment of Chihiro Location Network Co., Ltd. (hereinafter referred to as "Chihiro Location").
The Chihiro location operates the only ground-based augmentation system network covering the whole country. According to reports, the ground-based augmentation system of the Chihiro location has been basically completed, and more than 1,200 ground base stations cover the whole country, achieving precise positioning of dynamic centimeter-level and static millimeter-level. The high-precision equipment used by the base stations is all from domestic manufacturers.
Chen Jinpei, CEO of Chihiro Location, introduced the service of Chihiro location to identify urban elevated and landslide threats... The future Chihiro location service will become a public service like water and electricity, making it accessible and on-demand. use.
However, the Chihiro location encountered a problem encountered in all satellite industries, namely application bottlenecks. In Chen Jinpei’s words, “the depth of high-precision positioning industry is not so deepâ€.
