Electronic Total Station (Electronic Total Station) is a high-tech measuring instrument integrating light, machine and electricity. It is a surveying and mapping instrument system integrating horizontal Angle, vertical Angle, distance (oblique distance, horizontal distance) and height difference measurement. Compared with the optical theodolite, the electronic theodolite replaces the optical dial with the photoelectric scanning dial, and replaces the artificial optical micrometer reading with the automatic recording and display reading, so as to simplify the Angle measurement operation and avoid the error of reading. Because one time installs the instrument to be able to complete this station to measure the work completely, therefore is called the total station instrument. It is widely used in the field of precision engineering measurement or deformation monitoring such as overground large buildings and underground tunnel construction.
