A QDaedalus rendszer kalibrációja

Abstract

QDaedalus system is a computercontrolled automated geodetic total station completed with GNSS technology which can be used mainly for astrogeodetic measurements. Before the measurements, the most important step is to calibrate the instrument. Accordingly, it is necessary to establish a connection between the readings on the horizontal and vertical circle of the total station and the readings in the coordinate system of the CCD sensor. By the previous procedure at night in field conditions, the calibration was rather cumbersome and did not meet the exact measurement accuracy. To solve this problem, we have developed a new method and tool for calibrating more easily and more accurately. Studies were performed on the optimal calibration measurements and raster size; additionally, the temperature dependence of the measurements was also investigated. Our experiences are useful in all cases when installing a CCD sensor for geodetic instruments.
