Abstract: When carrying out geodetic work inside production shops or on a construction site, it is necessary to significantly change the focusing of the telescope. Refocusing the telescope can lead to a shift in the sighting axis, and, accordingly, to a decrease in the accuracy of angular measurements. The article presents the results of laboratory studies to determine the horizontal error of collimation and vertical index error of the Leica total station for distances from 2 to 84 m. Therefore, after checking the collimation and vertical index error and automatically taking into account their influence, it is allowed performing geodetic measurements at one position of the vertical circle. In particular, this makes it possible to speed up the execution of fan-shaped trigonometric leveling with short sights, which is performed when observing the settlements of the foundations of industrial buildings and structures.
