Abstract

Vertical refraction affects the results of trigonometric leveling. It is known that in the summer period, in the midday time, height differences measured by the total station are less than the true ones, and the angular errors can reach 20ʹʹ and more. During the experiment, on the basis of a length of 364 m, the geodesic method was used to determine the refraction coefficient in winter conditions, with the height of the sighting beam up to 1,6 m. The average coefficient was k=+ 2.3, i.e. in winter conditions, the measured height differences are greater than the true values, and the angular error was +13,5ʹʹ.
