The principle of the navigation function is described as follows:
Satellite navigation means that signals are transmitted from satellites to the ground. As long as the mobile phone supports satellite navigation, signals can be received. If the mobile phone receives signals transmitted from multiple satellites at the same time, the system with the strongest signals is selected for real-time connection to determine the device location. In many cases, multiple navigation systems are used when a mobile phone uses the navigation function. In an indoor environment, the satellite navigation function may not work normally. In this case, the mobile phone can infer the set location by using Wi-Fi and the cell location registered in the mobile network. Therefore, the accuracy of positioning information in satellite navigation is higher than that in mobile network positioning.
For users, the essence of the navigation function is to provide accurate and timely location information for users. Users should pay more attention to the accuracy of location information.
