Analysis of the possibilities to improve the leveling accuracy in turbulent atmosphere by taking into account the refraction and the change of angle I''

Lviv Polytechnic National University

Limitation of the geometrical leveling accuracy conditioned by leveling refraction influence and change of angle Ґ. Shown, that in the geometrical leveling the refraction errors have a systematic nature. After correction for refraction by some method, the residual refraction errors transform from systematic into casual, and that's is why are less dangerous. Them accumulation is proportion to root square from length of the leveling line - Л, and is not proportion to length - L. The recommendations on performance of the leveling works for normal and unsteady atmosphere stratification was given.
