- Preparation of electronic total stations (and electronic digital theodolites) for optimal astronomical observations. 14th International Multidisciplinary Scientific GeoConferences SGEM, 2014 June, Albena, Bulgaria (www.sgem.org). Abstract: Using electronic total stations (and electronic digital theodolites) in the process of making angular observations bring a whole set of advantages: electronic recordings of angles readings, the possibility of correction in real time of the angular observations from systematic errors components, the possibility of attaching of Charge-Coupled Device (CCD) image sensors for accurate readings of the angular values, the fast identification of the stars in the second position for robotic total stations, using the internal quartz clock for time registrations (timestamps), etc. The practical implementation of each of the above listed possibilities lead to inherent challenges: the physical attachment of CCD image sensors in the total station optical system, obtaining with accuracy of calibration values that enter in the calibration functions, bringing total stations automatically in the second position together with the specific diagonal eyepiece, time corrections for the internal clock, etc. In this article, the authors focus on obtaining accurate calibration values for calibration functions and investigate the possibilities of using total stations only in the first position of the telescope to conduct angular observations, with all the inherent advantages that result from this process.
