Introduction about the Total Station

A total station combines a digital theodolite and an EDM that work together with a microprocessor to rapidly and accurately perform tasks. With this combination, the total station can measure horizontal and vertical angles, slope, and horizontal and vertical distances. A total station also has a built-in calculator that performs trigonometric calculations, as well as an electronic field notebook used for storing data. The total station can interface with a computer for data transfer.

New Total Station Production represents a full set of the traditional surveying tools, new GPS receivers and software.
The approach based on the full integration of the satellite and traditional equipment, will allow ordinary consumers to increase considerably productivity due to the improved user qualities, full hardware and program compatibility inside the new Total Station complex systems.
EDM (Electronic Distance Measuring Device): An EDM is a device mounted on the top of the total station that sends out a light wavelength. The EDM measures the time it takes for the light to travel from the EDM to a prism, bounce off the prism, then return to the EDM. This measurement is displayed as distance, but it is really a measurement of time. Very accurate distance measurements are taken using an EDM.

Features of total stations

Total stations are capable of measuring angles and distances simultaneously and combine an electronic theodolite with a distance measuring system and a microprocessor.Angle measurement All the components of the electronic theodolite described in the previous lectures are found total stations.
The axis configuration is identical and comprises the vertical axis, the tilting axis and line of sight . The other components include the tribatch with levelling footscrews, the keyboard with display and the telescope which is mounted on the standards and which rotates around the tilting axis.
Levelling is carried out in the same way as for a theodolite by adjusting to centralise a plate level or electronic bubble. The telescope can be transited and
used in the face left and face right positions. Horizontal rotation of the total station about the vertical axis is controlled by a horizontal
clamp and tangent screw and rotation of the telescope about the tilting axis.
