Good day to all!

There is a small enterprise, which moves small trucks. The entire area of ​​the plant is covered with a wi-fi network, overlapping each other (aka Euler Circles).

If you specify the GPS coordinates of all wi-fi modules, can you find out the position of the truck inside the enterprise (ie, within the wi-fi networks)? If so, in what way?

Can there be other ways to calculate coordinates via WI-FI?

Thanks for attention!

  • And another question in dogonochka: It is necessary to determine the position of the car in a field with an area of ​​kilometer-per-kilometer with an accuracy of one meter. GPS and GPRS + available, one wi-fi tower can be installed - Avtostopom_do_Raya
  • Precisely gps - about 5 meters. For a 5x3 machine (average sizes for a small car), an accuracy of 5-10 methods is more than sufficient. But why is there a wifi ... I don’t know, especially since in normal conditions he will not cover a kilometer so easily. - KoVadim

Google does something like this in the adroids. So you can. The only thing that needs to be remembered is that the signal of the Wi-Fi is not constant, therefore it is better to average it.

Here is the article , how the man himself wrote triangulation.

    I'm not an expert, but I think you can use some kind of triangulation method based on the signal level from the WI-FI router, that is, calculate the coordinates of each router and then navigate by the signal level from them.
