The availability and stability of cellular communication can be achieved with areas coverage by base stations. Base station cellular (metal tower) is a complex and massive engineering structure which is usually installed on different buildings. Weight of tower with equipment exceeds 1000 kg. For security purposes of objects with installed cellular base stations you need constantly determine the operating characteristics of towers. One of the important characteristics is the deviation of the tower from the vertical. In the regulations for the operation of towers various ways of determining the deviation of the tower from the vertical are discussed. In the instructions it is proposed to determine the deviation of the tower based on observations with three or four starting points, between which there must be mutual visibility. After all dimensions processing we will receive a deviation of the tower from the vertical. The paper proposes a more simple method of determining deviations of the tower from the vertical with the use of electronic total station. The software of the instrument will improve the quality of the work. Measurements are performed from one point in topocentric coordinates system. Independent observations from a different point improve accuracy and serve as a control. Error of the results does not exceed 5–7 mm.
