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.
