About metric and angular dependencies of spatial straight line notches and their use in engineering and geodetic works

In applied geodesy tasks, it may be necessary to determine spatial angles. When bringing a 3D design of buildings and structures to the field with the help of an electronic total station (ES), it is important to verify the spatial angles between different elements of building structures such as roof overlaps, inclined anchors, and more, using the characteristic points' spatial coordinates. Modern geodetic instruments provide sufficiently high measurement accuracy (up to 1" and 1 mm, respectively).

Determination of permanent corrections of ball reflectors

Today, there are many manufacturers of triple-prism, spherical reflectors with different mechanical characteristics. That is why there is a problem of matching the signal reflection center with the geometric one. The purpose of this work is to evaluate the methods of determining permanent corrections of electronic tacheometers, ball reflectors and to develop recommendations for their use. Method. To determine the instrument correction, a displacement interferometer is used. It contains a two-frequency He-Ne laser with a wavelength of l = 0.63 μm (red range).

The possible uses of RTN-solutions for markup works on construction

The purpose of the research. Elaboration of practical recommendations concerning creation of a geodesic markup construction base with GNSS technologies, including Real Time Networks (RTN) methods. Methodology. To investigate the accuracy of the recommended solutions, different kinds of research were made, including a practical one. It was conducted on the construction site by marking the axis from two base lines, previously indicated by a GNSS receiver in such a way, so they coincided with the x and y axes of the general site’s plan.

Control of the major axes of rotary kilns using electronic total stations

The development of modern technique has led to the improved methods for the determination of geometric parameters of the big-sized rotary kilns. There are methods measuring of the rotary kilns axizes. It is shown, that use total station allow provide effective operation of this equipment.
