Urgency of the research. Technology of distance measurement with electronic total stations and electronic distance meters requires of definition of constant correction of rangefinder. Therefore, improvement of the method of determining constant correction electronic rangefinder is an urgent task

Target settingWe can observe integrated use of GNSS- technology and traditional methods that are most effective in localities with high-rise buildings, in wooded and mountainous areas. Among the traditional methods the most relevant method is the polygonometry. Method poligonometry involves the use of modern electronic total stations that are highly accurate distance measurement. For reliable determination of the distances you need to consider the value of the constant correction of the rangefinder.

Actual scientific researches and issues analysisThere are several ways to determine constant correctionThe most reliable way to obtain the constant correction is classical way on the basis of several lines. In field conditions used no-base alignment method that has several versions: with the installation of the tripods in the line and installation of tripods is not in line.

Uninvestigated parts of general matters defining. The no-base method with the installation of the tripods in the line is improved. Proposed to account for the offset of the middle of the tripod in plan and height to calculate a constant. This allows to expand the range of permissible displacements of the middle of the tripod. The range of valid offsets is defined for the medium tripod in plan and in height relative to the alignment line of the extreme stands for electronic range finders with the specified parameters exactly. For the practical implementation of the theoretical principles and results of mathematical modeling were carried out experimental research in the field conditions.

The research objective. The purpose of this article is the calculations of a constant correction electronic total station according to the results of experimental studies.

The statement of basic materials. Experimental studies to determine the permanent amendment of the Trimble 3305 DR paired with reflector of the electronic rangefinder ST-5 were made. 28 independent determinations were done. The distance between the extreme tripods was about 20 m. Slope of the terrain was 4 °, and deviation of the mean from a tripod line was about 20 m. Mean values of theconstant correction ents were calculated: - 41.1 mm - the procedure when tripods are arranged approximately in one line; - 41.0 mm - the procedure when the average tripod located outside the outer line of alignment; - 42.7 mm - when stripods are located in one line.

Conclusions. The no-base method with the installation of the tripods in the line in these conditions is not appropriate. It is suggested to perform the measurement and processing of the results of the no-basemethod with the installation of the tripods almost in the line. This will reduce the time to perform measurements by one third. Accuracy of determining constant correction is not lost.
