The purpose of the study is the development of calibration methodology of automated verticality monitoring system of radio communication masts and towers using geodetic measurements in order to obtain corrections in inclinometer measurements relative to the construction’s vertical axis. There are two different methods used for tower verticality determination: using Global Navigation Satellite Systems (GNSS) observations; three-dimensional terrestrial geodetic measurements using total station or traditional geodetic measurements methods.

A method has been developed for the adjustment of the results of measurements of length during calibration of a field comparator for verification (calibration) of distance meters and distance metric parts of total stations. The method of processing the results of comparisons of distance meters to the field comparator using the least squares method (LSM) was also developed on its basis. The additive biases of length measurements by each distance meter are evaluated according to the LSM, as well as the biases that are entered to the results of length measurements by each reflector.
