TESTING THE PRECISION OF THE ELECTRO-OPTICAL DISTANCE METER MEKOMETER ME 5000 ON THE CALIBRATION BASELINE ZAGREB

Abstract The paper examines the precision (accuracy) obtained with the Leica-Kem Mekometer ME 5000 distance meter on the calibration baseline Zagreb. A new method for the processing and analysing the measurements on the baseline is presented It provides an estimate of the precision, and, with thefrequency in the distance meter measured, the approximate accuracy as wel. For distances up to 100 m the standard deviation of distance measurement in one direction S = 0.058 mm is obtained For distances in the range of 100 to 3000 m, applying the proposed method of data processing, the standard deviation of a measured distance (measured forward and backward, and on the basis of adjusting all measurements on the baseline) srDII = 0.12mm + 0.21mm. D km was obtained in 1988, and in 1996 s′rDII = 0.07 mm − 0.13 mm.D km + 0.37mm.D2 km .
