The aim of this article is to investigate the accuracy of dual line leveling, and develop a methodology for its execution to enhance the precision of elevation determination by accounting for vertical refraction and controlling the non-horizontality of the leveling beam. Methodology. Considering that digital levels can measure distances to the rod and account for the non-horizontality of the beam and vertical refraction during measurements, we propose a method of dual line leveling.

The purpose of this work is to analyze the results of the study of the dynamics of vertical movements of the permanent station of the GNSS positioning system «Poltava» (identifier POLV). Method. A geodynamic test site was set up on the territory of the Poltava Gravimetric Observatory. It includes rappers with known stability indicators laid at different depths. The exact level of H‒05 is set on the A1 standard, which is characterized by high stability over 30 years of observations.

Obtain working formula for determining trustworthiness information about vertical drift of the pipe bore-hole out of account of the own weight.
