Positioning satellite service is a high-precision positioning service provided by China Unicom CDMA 1X network with advanced GPSONE positioning technology. The positioning accuracy is as high as 5 meters to 50 meters in outdoor environment. At the same time, no matter indoors or outdoors, as long as the CDMA 1X network covers the place, positioning can be realized and the positioning time can be shortened. Unicom's infinite positioning star service is based on the positioning of mobile terminals, and combined with GIS (Geographic Information System) map data information, it can provide users with rich location information services.

Interactive horizon service is a wireless Internet service provided by China Unicom for CDMA users. As long as the mobile phone terminal supporting the browser function above WAP 1.2 is used, its operation is similar to that of China Mobile's WAP positioning. At present, Unicom's data communication tariff standard for mobile phones is 0.0 1 yuan /kB.

Here we illustrate the use of GPS through an example: when you enter the positioning function, a satellite image will appear on the screen. After a few seconds to ten seconds of inquiry, the description of the current location of the mobile phone will be displayed on the screen, such as "Wanquanhe Road, near Wanquan Xinxin Home". At this point, the user can further query the map of the current location, the bus transfer route to a certain place, and the restaurants and restaurants around 500-2000 meters. If you continue to query "Parkson" and search Parkson Shopping Center, you will be given the detailed location and contact number of Parkson, and the bus transfer route from the mobile phone location to Parkson will be displayed.

Do you find it convenient to read the above description? Especially for some natural "road blind" friends, the mobile phone positioning function will definitely help you solve many travel problems.

Global Positioning System (GPS) is a new generation of space satellite navigation and positioning system jointly developed by the United States Army, Navy and Air Force in 1970s. Its main purpose is to provide real-time, all-weather and global navigation services for land, sea and air, and it is also used for some military purposes such as intelligence gathering, nuclear explosion monitoring and emergency communication. It is an important part of America's global dominant strategy. After more than 20 years of research and experiments, it cost 30 billion dollars. By1March 1994, 24 GPS satellite constellations with global coverage of 98% had been deployed.

Mobile phone positioning SMS version

SMS version of mobile phone positioning can be used nationwide, generally in the province can be located to a more accurate location, after the province can be located to a specific area name (according to the area code to distinguish). The short message fee is 0. 10 yuan/message, and the information fee is 6 yuan/month, which is generally equivalent to the monthly fee.

WAP version of mobile phone positioning

As long as you have a WAP-enabled mobile phone, you can directly connect to the Internet through wireless and get your current location. If you are in Zhejiang Province, start your own WAP browser on your mobile phone, enter the URL in the browser, and click the menu to enter the business, then you can find your own location.

Other mobile phone positioning

This is a new mobile phone positioning technology. But because it involves invasion of privacy, it has never been known to the general public. This kind of mobile phone positioning is not traditional GPS positioning, but based on the feedback of base station information signal to lock the position of mobile phone. Which is the law. So far, this mobile phone positioning method is only used in public security technology to solve crimes. You only need to know the mobile phone number, and the owner can lock the owner's position when the signal is turned on. Because LBS is interfered by base station signals, weather, radio waves and other signals, its accuracy is not particularly ideal. The urban area is about 50M-200M.

At present, most provinces in China need the authorization of mobile phone users to use mobile phone positioning.

Mobile phone location service has a huge industrial chain lineup beyond traditional value-added services, which consists of mobile operators, system equipment providers, terminal manufacturers, GIS developers, application providers, middleware providers and other links. It comprehensively uses technologies and applications including mobile communication, satellite navigation, Internet, geographic information system, integrated information service, etc. It is the product of multi-industry and multi-technology cross-integration. Mobile phone location service needs continuous and huge investment, especially in network upgrade and electronic map.
