Annotation: The technology of geodetic control of the sag of the detachment of mast structures under operating conditions, using non-reflecting electronic tacheometers, is given. The proposed method allows effectively and accurately in a short period of time to determine the sag of the boom necessary to control the tension force of the braces and, if necessary, adjust it. The substantiation of the optimal marginal error of determining sag on the basis of the marginal error of determining the tension of delays is given. The accuracy of individual measurement sources was calculated, in particular, the effect of errors in angular and linear measurements on the accuracy of trigonometric leveling of mast construction delays. The influence of the error in guiding the telescope of the electronic total station to the center of the delay is considered.
Keywords: sag of delays, geodesic control, accuracy calculation.
