Beidou navigation accuracy to 2.5 meters

Recently, the positioning accuracy of the fourth-generation high-performance Beidou/GPS navigation chip developed by China Aerospace Science and Industry Corporation reached 2.5 meters, and the performance metrics such as capture sensitivity and tracking sensitivity all reached the international advanced level. The successful launch of the chip will revive the car positioning and navigation market.

2.5-meter positioning accuracy of the chips leading international leader According to publicly available data, there are currently a total of four sets of navigation and positioning systems worldwide, namely the Global Positioning System (GPS) Global Positioning System, the GLONASS system, and the Galileo Positioning System. System and BeiDou Navigation System. At present, the most mature application is the new generation of space satellite navigation and positioning system jointly developed by the US Army, Navy and Air Force in the 1970s. This is the GPS navigation system we commonly call. The GPS navigation system is a radio navigation and positioning system that provides information such as three-dimensional position, three-dimensional velocity, and the like to all over the world based on 24 positioning satellites around the world. It consists of three parts, one is the ground control part, consisting of a master control station, a ground antenna, a monitoring station, and a communication aid system. The second is the space part, which consists of 24 satellites and is distributed over 6 orbital planes. The third is the user device part, which consists of a GPS receiver and a satellite antenna. Civilian positioning accuracy can be up to 10 meters.

According to the latest news, China's self-developed Beidou navigation chip technology has been able to successfully accurate to 2.5 meters, which has reached the international advanced level. Advances in technology have made it possible to use a wide range of navigation system technologies in China.

The simulation chart opens the on-board monitoring Xin Lanhai Academician Liu Jingnan of the Chinese Academy of Engineering once said in public that although the US GPS has currently monopolized more than 95% of the domestic navigation industry, the unique technical advantages of the “Beidou” will gradually emerge in practical applications in the future.

According to industry insiders, as the Beidou navigation technology advances, the on-board surveillance market may usher in a new explosive growth. “The traditional car market GPS has taken a dominant position, but with the progress of the Beidou system technology, more and more consumers will be optimistic about and use the Beidou navigation system.”

It is understood that the Big Dipper 4th generation chip has successfully won the bid for the "Shaanxi Provincial Public Security System Policing Vehicle Satellite Positioning Management System" project. This project is the first province-level Beidou application project in the field of policing vehicle management in the public security system in China, and Shaanxi Province's public security agencies have installed a total of more than 10,000 vehicle terminals in all types of police vehicles. After the completion of the system, Shaanxi Provincial Police will be fully enhanced. Service efficiency.

Some on-board monitoring companies also stated that many products currently adopt Beidou and GPS dual-mode products to successfully meet the development needs of the automotive market. "The implantation of dual-mode vehicle monitoring allows users to freely select the navigation mode. It greatly facilitates the user," said the industry insiders.

In addition, according to media reports, on August 9th, the China Satellite Navigation and Positioning Association and the China City Gas Association signed a strategic cooperation agreement in Beijing, fully supporting the construction of a gas-based Internet of Things system through the precise location service of the Beidou satellite navigation system, and fully enhancing China's urban gas enterprises. Underground pipe network security management level. This is an important part of the priority implementation of the “100 cities, 100-by-400” action plan, and will also bring more than one million terminal consumption to the Beidou system. Analysts pointed out that as a symbol of this cooperation agreement, the "100 cities, 100-pronged, and 100-pronged" action plan will realize the interconnection of 100 selected city location networks and carry out 100 location service application demonstration projects, which also means the civil use of the Beidou. The process is significantly accelerated and real-time landing. Under the leadership of the military industry, government, and industry applications, the Beidou industry will usher in high-speed development opportunities. It is recommended that investors capture investment opportunities from three main lines, including terminal manufacturers with autonomous chip R&D capabilities, navigation map leading companies, and positioning service providers.

China Creation Securities pointed out that since the beginning of last year, the Beidou-related policies have been intensively released, which reflects the country's determination to promote the Beidou industry. Under the strategic environment of the government, Beidou has already broken out in the ** market, and the civilian market will follow suit. As of the end of 2013, China's Beidou Terminal has more than 1.3 million social holdings. Under the impetus of related policies, the civil market in Beidou has exploded.

It takes time to build a mature industrial chain. It is understood that with the mature application of GPS and BeiDou system technology, it is increasingly sophisticated. From the chip to the board, the whole machine, and related software applications, the satellite navigation industry chain is currently gradually building and perfecting in China.

Liu Jingnan once said that the maturity of the industry chain is mainly due to the advancement of GPS applications in China over the years.

Liu Jingnan once said that technically, there is no obstacle to the formation of China's navigation industry chain. The key to the future is to further follow up on market operations, business models and demand expansion.

As far as the satellite navigation industry is concerned, at present, China has initially formed an industrial chain with satellite navigation signal provision, technology research and development, product manufacturing, engineering system integration, and application and operation services as important links.

"But the entire industry chain is still very imperfect and it is not perfect," the industry sources said.

In recent years, all relevant state agencies and local governments have used the “Beidou” as an important starting point for new industries, and promoted the development of strategic emerging industries, which also led to a clear growth trend in the entire satellite navigation industry.

Although the state is pushing for navigation development, it will take time to mature the industry chain, but the momentum of development has become unstoppable.

The China Satellite Navigation and Positioning Association estimates that by 2015, the output value will exceed RMB225 billion. The total social holding of navigation and positioning terminals is expected to reach around 500 million units, and the output value in 2020 will reach 400 billion yuan. The total social holding of navigation and positioning terminals exceeds. One billion units. Some experts predict that the Beidou system application will account for 80% of the domestic market and 20% of the international market by 2020. According to the development target of the “Long-Term Development Plan of the National Satellite Navigation Industry”, the compound growth rate of China’s satellite navigation and location service industries will reach 22% in the next seven years, and the compound growth rate of Beidou and its compatible products will reach 67%.

According to the National Medium and Long Term Development Plan for Satellite Navigation Industry promulgated by the State Council in September 2013, by 2020, the innovation and development pattern of China’s satellite navigation industry has basically taken shape, the industrial application scale and internationalization level have increased substantially, and the industrial scale has exceeded 400 billion RMB. Yuan and BeiDou satellite navigation systems and their compatible products have been widely used in important industries and key areas of the national economy. They have gradually been popularized in the mass consumer market, have contributed 60% to the domestic satellite navigation application market, and have reached over 80% in important application fields. , With a strong international competitiveness in the global market.
