FIELD: measurement equipment.
SUBSTANCE: three functionally combined test benches, which are located on individual isolated foundations, provide a common metrological base at calibration of metrological parameters of a calibrated instrument and build-up of a geodetic network with known sampling length of reference geodetic rod and prism-polygon. Calibrations of rectangular coordinates X, Y, Z, as well as horizontal and vertical angles and distances are performed from one installation of the instrument. As per measurement results, by levelling geodetic networks designed through length and number of packings of the reference geodetic rod, systematic and random measurement error components are obtained by the calibrated coordinate instrument along three orthogonal axes in working range.
EFFECT: higher accuracy.
