WebIt avoids rotating the coordinate system, but it may not be the best. There are 2 solutions to the trilateration problem. To get the second one, replace "- sqrtf" by "+ sqrtf" in the quadratic equation solution. Obviously you can use doubles instead of floats if you have enough processor power and memory.
