Electronic total station from the moment of its appearance was confirmed when working on large-scale surveys, Stakeout, is an indispensable instrument in the supervision of construction. When performing any work, the question inevitably arises about how the results of the measurement correspond to the true? In this paper, we investigate the accuracy of the measurement results the following inherent in the program measurement electronic total station (ET) “Topcon”-105: the determination of the excess, determination of position, measurement of inaccessible distances, measuring inaccessible heights in two modes (“height of the reflector”, “height of the reflector is unknown”) the program “Stakeout”, program “the tick” in two modes (“distance” and “angles” ). Before the start of the research were done a lot of preparatory work. In discussing the research agenda was outlined several stages of works. The first stage was laid for a network of 33 points on the geodesic polygon October oil College. Then, the method of poligonometrii class 4, the measurements conducted at the fixed network. The coordinates of points obtained from processing using the program “Credo–Date”. Mark points obtained from geometric leveling of class II. It was further selected and prepared instruments for research. The next stage of prioritized research programmes ET at the site. At the final stage, performed field measurements with the accuracy assessment.
