Nereid, I think the laser shootings would have to be at least a 100 miles minimum, and an angle greater than lets say 15 degrees to be able to detect such a small difference with today's equipment -- and for the results to be decisive statistically. |
How did you arrive at this conclusion?
Please quote your source(s) wrt the precision and accuracy of "
today's equipment".

I'm hoping to shoot at least a 30 degree angle for a minimum of 100 miles. First I would shoot on the horizontal to confirm a null result. I would then switch the position of the instruments and test again. After confirming a null result I would then do the setup and shoot at an angle. After getting the results of many hours or days of countless shootings I would average the results one way vs. the other. After getting the results I would reverse instruments and repeat the testing.

And all of this would be done through the atmosphere, right?
How do you propose to obtain a 100 mile sightline at an angle of 30 degrees (from the horizontal)?
What variations do you expect, in the results, due to the inhomogeneities of the atmosphere (both in time and space)?
