Electronic tacheometer 6Тa2


The tacheometer is designed to perform large-scale topographic surveys for the creation of networks of planned-altitude justification, to perform executive surveys of built-up territories and those under construction, for automated solution in the field of various geodetic and engineering tasks using application programs.
