Beidou navigation began civilian navigation system-Beidou satellite, Beidou, GPS-IT information Beidou navigation began civilian
Beidou satellite navigation systems (hereinafter referred to as "Beidou") civilian is ineluctable.
Meanwhile, the glory days of handheld GPS have been slipping away.
Previously published the white paper on China's satellite navigation and positioning service industry development (hereinafter referred to as white paper) in 2013, China's satellite navigation and positioning service industry overall value of more than 104 billion dollars in 2012, added 28.4%, with big production value of more than 10 billion yuan, up to 9.8% per cent. Total sales exceeded 348 million of our navigation and position Terminal. Navigation smartphone sales reached 330 million units.
The future, has made this figure may continue incrementing.
Yesterday morning, in Hangzhou to attend "deepening Beidou industrial strategic cooperation agreement" at the signing ceremony, Chinese people's Liberation Army General staff said Xue Guijiang Secretary for surveying and mapping the navigation, by 2020, to launch more than 30 employees Beidou navigation satellites in China, the goal of complete global coverage, with global service capabilities.
This means, Beidou system can more coverage, accuracy, higher services for users.
Historical background
A matter of national strategy and information technology needs
Beidou system to promote home-made navigation system of alternative
Market prospects
Provides navigation, location, timing, exchange of information, licensing, safety certification, call services, solutions, multimedia applications, product display, Beidou navigation services such as technical training, Big Dipper in the marine, transportation, weather, construction, agriculture, electric power, telecommunications and many other industries, facilitate the formation of regional Beidou operation service system.
Speaking of navigation, many people's first reaction is "GPS". Indeed, from the United States has cornered the market in China for global satellite navigation system navigation products 90% per cent of the market. However, one run by China's own construction, independent of Beidou system fame.
Xue Guijiang said the Beidou system research began in 1994, the real "Fame" is in the Wenchuan earthquake relief period. At that time, the ground communications are interrupted, Beidou unique position reporting and communications features these two features play a huge role.
At present, distributes dozens of navigation and positioning satellites in space: United States 32, Russia 29, China 14-4 European Union. Among them, the United States GPS is currently only able to provide global navigation, positioning and timing services for satellite navigation systems.
However, from the communications function, unique advantages of the Beidou system. Xue Guijiang says, this is due to the Big Dipper generation two-way communication systems design. So-called bi-directional communication refers to users and users, between users and the central control system can achieve short digital two-way message communication and GPS is available only for one-way communication, the receiver can only passively receive satellite signals cannot be active signals.
Expert, who declined to be named said that the last centimeter are used in surveying and mapping GPS, I have to admit, GPS mapping and high-precision measurement of this is in the area of technical means.
But using hidden GPS is relatively large, built over more than 2000 stations in China, the data are classified as State secrets, if the use of foreign software, security would be a problem.
Meanwhile, satellite navigation and positioning system is one of the national information infrastructure, the big industry is beneficial to improve China's economic and social Informationization and information security. Only domestic alternative, there is a big market, as development was increasing, market space will be larger in the future.
Beidou satellite navigation experimental system of engineering construction in China, the regional system, the global system, "three-step" development strategy.
Xue Guijiang said the Beidou system construction of "three-step" are the satellite navigation experimental system was completed in 2000, the "Beidou"; the end of 2012, "second generation" systems covering the Asia-Pacific region, and according to the plan, the third step is around 2020, built 35 satellites, global networking, better home-made navigation system.
Zhejiang Provincial Party Committee and provincial government to advance the national strategy for four major service, as well as the intelligent deployment and application needs of urban construction of demonstration pilot, the first in the wisdom marine, urban safety management, emergency response, special and public transport information service, in-car information services, modern logistics, areas such as high-precision timing, prioritize the Beidou system mature technologies and products to speed up key industries of the Big Dipper.
Everywhere using GPS Beidou system
Each mobile terminal needs Beidou system
Insiders said that satellite navigation is not only a matter of national security, but also is closely linked to information consumption, human services.
Especially with the navigation system automatically into most mobile handsets, functionality for locating began to gain ground, it also meant development of the satellite navigation and location services industry has entered a golden age.
Hangzhou Committee through a letter and information resources associated with infrastructure branch official said that from the perspective of the future of China, where he could use GPS systems are used to the Big Dipper, high-precision products requires the Beidou system, vehicle monitoring systems also have to use the Big Dipper.
Later, standard configuration is the ability to locate mobile Internet industry. Each phone, each terminal requires positioning, location services, can be used to locate places, were able to use the Big Dipper, and positioning are essential elements of the information society in the future, get location information, get location service, infrastructure is very important.
Xue Guijiang says, the military-civilian cooperation in Zhejiang Province was chosen because the rapid development of the information industry of Zhejiang Province, in areas such as big chips, modules, Terminal, has formed a certain industry. This means that future both sides will promote autonomous satellite navigation technology in Zhejiang province took the lead in promoting, promoting industry healthy growth the Beidou system.
According to the data provided by the provincial Committee through a letter shows, in 2013, the informatization index stood at 97.98, Zhejiang Province, ranked third, behind only two municipalities of Beijing and Shanghai. Moreover, speeding up the construction of next-generation information infrastructure upgrades and 20 Smart City pilot demonstration project is on track, application of Beidou system in Zhejiang has created basic conditions and a broad market space.
Strategic cooperation
Beidou system is China's own development, run on its own global satellite navigation system, with the United States global positioning system (GPS) and Russia's GLONASS system, the European Union's Galileo positioning system, recognized by the United Nations core supplier for the global satellite navigation system.
Strengthen the system construction, the integrity of the technology, availability of technology, signal simulation and its application in detection technology, product, standard specification for joint research, innovation and core technology of satellite navigation applications.
Agreement in the future, both sides are going to serve the national strategy to promote comprehensive, coordinated and sustainable development of economy and society, explore the accumulation combine forces with the people, development of innovative empirical models to promote autonomous satellite navigation technology in Zhejiang province took the lead in promoting, promoting the healthy growth of Beidou navigation application industry. Specifically, the two sides will strengthen strategic cooperation in 5 areas.
Xue Guijiang said that in 2015, complete integrated enhancement system, Beidou industrial application of bucket Foundation North of demonstration for representatives of key projects, advance priority to safeguard the marine economic development, focusing on urban public safety management a number of government projects.
Yesterday, Beidou Industrial Alliance was officially established in Zhejiang Province, to open up the industry chain of communication research, manufacturing, application, operation and docking, in collaboration with the ability to enhance innovation and market.
"After the Beidou system, and product cost little, product performance has greatly improved. In the long run, the Beidou system development prospects are very good. "Hangzhou hongquan systems digital equipment limited company is very bullish on the Big Dipper's future, he said, now mobile phone chips, a couple of years, BD will develop.
Total support for the joint formation of Compass platform company in Zhejiang Province, Zhejiang Beidou location information services, promote the development of its regional Beidou industrial mixer.
Hangzhou high-tech industrial base, "geographic information industrial park of Zhejiang Province" for the support to build national Beidou navigation application (Zhejiang) industrial base.
