Prompt all known methods for determining the coordinates of the location of the user. I only know GPS. What determines the error in determining the coordinates and within what limits? And if the application determines my coordinates, what communication tool does it use for this?
- I am not an android developer and probably the sutra will tell you something in more detail on android, but for now I can say that 3 + 1 satellites are used to determine the coordinates by gps and this location is very accurate, its error can hardly be more than a meter. If the work with gps receiver is not available, then the location is determined using cell towers (the device works with the near one) and the error can reach tens of meters. I cannot guarantee the accuracy of the information, I try to help with what I can ... maybe someone can help me :) - fogipoziw
- in addition to the above, more coordinates are determined by the available WiFi networks. Moreover, it is not even necessary to connect to them. The essence is the same as with base stations - the usual triangulation. You can also determine the data from the operator, but for this you need to agree with the operator. I also saw a way - with the help of bluetooth. It scans the available bluetooth nearby, and for some you can get their coordinates. - KoVadim
