Disadvantages: The positioning accuracy is not as good as GPS mobile phone positioning, and the urban area is basically about 10 meters.

Note: This positioning technology must be authorized by the communication operator before it can be implemented, and ordinary individuals basically cannot know about it. Second, the satellite GPS navigation and positioning method is closely related to the GPS (United States) that we use daily.

Because the satellite signal can be used to carry out real-time three-dimensional navigation and positioning and velocity measurement on a global scale, the accuracy of this method will be relatively high.

WiFi signal positioning: Locate the located mobile phone through the wifi signal Advantages: There is no need to install software on the located mobile phone, only need to open the wifi function, and the nearby network hotspot can be scanned to achieve positioning.

Disadvantages: Positioning intensive reading is not enough, similar to base station positioning, about 10 meters. It has been the three major technologies of current positioning, but it is not so simple to realize the mutual positioning and picture presentation between two mobile phones.

iPhone: By clicking on the phone's settings - privacy - location services - common locations - history, you can view the phone's past records, accurate to what time it appears**.
