On another note, what if we had a rotating laser, that had a spectrum up and down.
And, since it was rotating at a constant rate, we could set out 2 targets. It would register one, then the other. By time lapse, we could compute the horizontal angle difference between the targets. From the spectrum of the return, we have the vertical angle. Then, the last item is distance. Not too sure how to get that. To use this system, you take the LS to a point, and shoot a coordinate. Then, set a plumb stake on that coordinate. That has a little passive target, with a particular shape, or symbol on it. This gives a return, and registers as a "Backsite". Now, we move the LS to point 2, and store it's coordinate. The rotating laser is below the LS. Now, we take the second target, on a little pole, and walk around. We have with us a TABLET pc, that is WIFI to the LS. We set the little rover pole on a pipe, and it registers the horizontal angle difference, from the BS to FS. Since it is a fairly tall and narrow beam, it also has a spectrum. This gives us a vertical angle. Still not sure how to get the distance.
But, this would allow the LS to do offset surveying, in a small area, within WIFI range.
