You can’t use the GPS technique because the timing is nothing like accurate enough. The best you can do is Trilateration based on the signal strength from each base station and assume that range is proportional to signal. You will probably need to force a connection to each base station in turn in order to … Read more

The conversion is: x = R * cos(lat) * cos(lon) y = R * cos(lat) … Read more
