Errors of electronic high precision short distance measurement

Popis výsledku v původním jazyce

In modern industrial geodesy, high demands are placed on the final accuracy, with expectations currently falling below 1 mm. The measurement methodology and surveying instruments used have to be adjusted to meet these stringent requirements, especially the total. That is why is very important determination of the real accuracy of measurements at very short distances (5–50 m) because it is generally known that this accuracy cannot be increased by simply repeating the measurement because a considerable part of the error is systematic. This article describes the detailed testing of electronic distance meters to determine the absolute size of their systematic errors, their stability over time, their repeatability and the real ac-curacy of their distance measurement. Based on the experiments’ results, calibration procedures were designed and a special correction function for each instrument, whose usage reduces the standard deviation of the measurement of distance by at least 50%.
