Modern geodesic instrument and methods of metrological control are presented. Specifics of tachymeter metrological control are considered. As an example, the Odessa reference linear basis of geodesic polygon consisting of 7 fundamental geodesic stations situated on the plain and seismically safe site is presented. A number of problems concerning the use of the existing standards are stated. The concept of a new method of tachymeter metrological control is suggested. The purpose of the new method is to create an additional stage of metrological control to allow qualitative and efficient metrological control of tachymeter that had not been subject to verification procedure previously due to various reasons. Investigations in connection with the use of the new method of tachymeter metrological control were carried out on the existing experimental reference base. The article presents the calculation of the mean-square error in measuring distances by way of multiple measuring the reference base lines.

Current measuring means of large linear dimensions as well as the existing methods of their metrological control are examined. The concept of a new method of metrological control of total stations is proposed.
