    Charakterystyka wybranych cech funkcjonalnych tachimetrów elektronicznych
    (Wydawnictwa AGH, 2006) Buśko, Małgorzata 
    The paper includes a brief characteristics of the selected design solutions of modern electronic tacheometers. These instruments are systematically improved due to scientific progress in such fields like electronics, optics, information technology and precision mechanics. The subject of the detailed discussion in this paper was a principle of operation of the main axis vertical swing compensation system of the instrument, the system to enable automatic aiming of the tacheometer telescope at the reflector, and tracking of the moving prism and possibility to conduct distance measurements without using a reflector. Tacheometers made by Topcon, incorporating the above mentioned features, were used in field and laboratory surveys. Laboratory distance measurements were related to the reference values, obtained based on measurements taken by laser interferometer HP5529A. The performed measurements enabled to formulate the conclusions, regarding the application capabilities and limits of tacheometers in geodetic practice, particularly in the aspect of non-prism measurements.

    Comparison of the effectiveness of automatic targeting, using systems of ATR type, with manual targeting, based on full test procedure ISO 17123-3
    (2010) Owerko, Tomasz; Kuras, Przemysław; Szafarczyk, Anna
    The subject of the article is to compare the accuracy of targeting implemented in two manners manual and automatic. The study was conducted based on international standard ISO 17123-3 for two theodolites equipped with the automatic target recognition system. The paper discusses surveying procedure - a full testing procedure, which allows to determine the actual accuracy of the tested instruments. The obtained values are the basis for conducting statistical tests that allow to verify the presented hypothesis.
