TESTS RESULT
We tested this function and here is the result.
Point 1 is the coordinate of the point we need to survey.
Point 2 is the coordinate calculated by FG in three pole tilt intersection way.
Point 3 is the coordinate calculated by FG in two pole tilt intersection way (selected point A).
Point 4 is the coordinate calculated by FG in two pole tilt intersection way (selected point B).
As we can see, point 2 and point 3 are matched with point 1 very well. And by refering to the draft we draw, we can know point 3 is not the real point we need to measure.
So our suggestion is, if you think judging point in two pole tilt intersection is complicated, you can use three pole tilt intersection directly.
