3.2.2 Setting Atmospheric Data
Refraction modules:
The instrument will automatically correct the effect of atmosphere refraction and
the earth curvature when calculating the horizontal distance and the height
differences.
The correction for atmosphere refraction and the earth curvature are done by the
formulas as follows:
Corrected Horizontal Distance：
D= S * [cosα+ sinα* S * cosα(K-2) / 2Re]
Corrected Height Differentia：
H= S * [sinα + cosα* S * cosα(1-K) / 2Re]
If the correction of atmosphere refraction and the earth curvature is
neglected, the calculation formula of horizontal distance and the height differentia
are:
