The article presents an effective method for determining the tilt of transmission line supports located in cramped observation conditions. It has been established that if the center of the support is visible from only one reference point, the proposed method is the most effective and less labor-intensive compared to other methods for determining the tilt of supports. The technology for performing angular and linear measurements using a reflectorless electronic tacheometer is described in detail. A detailed calculation of the accuracy of angular and linear measurements is performed. It is established that the main influence on the accuracy of determining the tilt of supports is exerted by errors in angular measurements. It is shown that under construction conditions, angular measurements should be performed with an error of no more than ±4"», and under operating conditions – no more than ±8". A technique is given for determining the directional angle of the tilt vector, which is necessary in the case of aligning supports with an unacceptable tilt. Key words: geodetic monitoring, chimneys, cramped conditions, measurement error, measurement accuracy, construction roll.
