INVESTIGATION OF THE REFRACTION INFLUENCE ON LEVELLING RESULTS RECEIVED WITH A DIGITAL LEVEL AT NEGATIVE TEMPERATURES
The article shows the results of a study on the effect of vertical refraction on the results of leveling using the digital level of the Trimble Dini 0.3 model under negative temperatures at a distance of 25 and 50 m. The results of the leveling showed that vertical refraction strongly influences the accuracy of measurements.
