Use of tilt compensation, on a monopod. Let's discuss monopod use.

[Nate The Surveyor]

I was out last wk, surveying a small creek. It was some 3' wide, and ran for some 400', winding along.
I decided to try the tilt-monopod thing. It seems to me that there are some advantages for using the tilt compensator. It ran like a million bucks. It seemed to run significantly faster.

I'm looking to see if I'm right on this.

IF you were standing in the woods, looking down through the woods, to see if you could see survey instrument, you would move back and forth, until you found a more open corridor, to make into your traverse line, to reduce the brushing, or eliminate it altogether. Then, your wobble is useful.

In a sense, (maybe) this is what the LS is doing. Since the point (tip) is stationary, and the height of rod is known, and you are wobbling around, and if you move a few tenths one way, then another, you can sometimes significantly change the multipath environment, during this action. Since the LS knows that the pole tip is stationary, it can process things, and reduce all your wobbling action, into one point. While, the wobble changes the multipath route to the satellites. So, wobbling takes the place of time, for the Sats to change, as they are in motion, across the sky.

Am I right about this? This could signifigantly change how I USE the LS.

Please talk to me, let me know if my imagination is on the right track, or if I need correction, or more info.

Thanks!

Very interesting, I have noticed this before even with my epoch 50s and find myself giving a quick wobble to the pole when I am trying to get a fix in a bad spot. I haven't really tried what your speaking of, but it is interesting. Another thing that I have noticed is that if I rotate the LS (it's on a Leica quick connect so you can just spin around) it will help it get fixed sometimes.

Adam, it's funny you say that. I used the EPOCH 50's extensively and I would give my Rover a slight wobble just like you described.

Standard Operating procedure for them, mine are pretty much paperweights now.

Good idea Nate. I had not considered using tilt correction in conjunction with the wobble. It should work and yes the wobble does help the receiver to fix. I seldom do it though because I don't typically use tilt with control points.

For what it's worth, it might be a handy mechanism, to do one last check, of an important corner.
