The precise positioning of mobile phones mainly depends on the rigorous setting of mobile phones, the high sensitivity of software and the development of satellite facilities.
Mobile phone positioning: Mobile phone positioning refers to the technology or service that obtains the location information (latitude and longitude coordinates) of the mobile phone or the end user through a specific positioning technology, and marks the location of the located object on the electronic map. There are two kinds of positioning technologies, one is based on GPS, and the other is based on the positioning of base stations in mobile operating networks. The positioning method based on GPS is to use the GPS positioning module on the mobile phone to send its own position signal to the positioning background to realize the positioning of the mobile phone. Base station positioning is to determine the location of the mobile phone by measuring the distance between the base station and the mobile phone. The latter does not need the mobile phone to have GPS positioning ability, but the accuracy depends largely on the distribution and coverage of base stations, and the error will exceed one kilometer. The former has higher positioning accuracy. In addition, there is another way to locate in a small area by using Wifi.
