Bogdanov S. The procedure for determining and consideration of the influence of vibrations on precision of measurements of electronic geodetic instruments

The object of study - digital levels and total stations in the measurement of distances, horizontal and vertical angles, determining the coordinates and altitudes of points. The aim of the work is to solve scientific and applied problems of definition and before the effect of vibrations on the measurement accuracy total stations and digital levels. Methods of investigation based on the use of statistical analysis and analysis of variance. To determine the assessment of the accuracy of the measurement results in a vibration mathematical models by the method of least squares (OLS). Scientific novelty. Is to obtain theoretical and practical results in solving scientific and applied problem of vibration on the measurement accuracy of electronic surveying instruments, namely: Experimental study of the effect of vibrations on the accuracy of modern electronic total stations and digital levels; defined resonant frequency and vibration resistance parameters of devices; applied software environment «MathCad» to validate the data and a mathematical relationship between the frequency and amplitude of vibration; developed and theoretically substantiated model of measuring horizontal and vertical angles in terms of vibration, which allows you to assess the accuracy of the relationship between the frequency and amplitude of vibration; based on experimental data and theoretically grounded to choose the optimal mathematical model of removal of samples; developed recommendations to reduce the impact of vibrations on the accuracy of geodetic measurements of electronic surveying instruments. The practical significance of the results is to obtain a real range of frequencies and amplitudes of vibration, which enable us to determine the parameters of vibration resistance and vibrochuvstvitelnosti electronic surveying instruments in terms of vibrations. Practical advice and the results of theoretical and experimental studies allow you to use when performing geodetic measurements on hydro power and industrial facilities, that is, to carry out measurements in areas of exposure.
