Rangefinders to obtain a length measurement error standard error determined the order of mD = ±(1 mm + 1 ppm) or less are in the group precision rangefinders. Rangefinders are applicable in the measurement of displacement, in the industrial measurement of short-range models, and as the length of the measuring equipment service points. Full use of this equipment requires a comprehensive examination. The paper gives examples of precision rangefinders research different companies: Leica, Trimble and Sokkia. Rangefinders Laboratory tests were performed in Metrologic Geodetic Laboratory of the Faculty of Mining Surveying and Environmental Engineering of AGH UST in Krakow. These measurements included the determination of cyclic errors in the 30 m based on the HP5529A laser interferometer. Field pattern of the length of a test baseline "Wisła" with a length of 1230 m is located on a stretch of the flood embankment of the river Vistula. It consists of 20 columns with heads measuring Kern enable forced centering. On the basis of measurements to determine the constant addition of the total set of EDM-reflector and rangefinder patch scale. Proposed the use of low-pass filter to optimize the calculation of atmospheric corrections to the measured length. (original abstract)
