Background technique

The surveying and mapping instrument is a high-tech measuring instrument integrating light, machine and electricity. It is a surveying and mapping instrument system integrating the functions of horizontal angle, vertical angle, distance and height difference. Compared with the optical theodolite, the electronic theodolite uses the optical dial. Replace the photoelectric scanning dial, and replace the manual optical micrometer reading with the automatic recording and display reading, which simplifies the angle measurement operation and avoids the generation of reading errors. Before the GPS surveying and mapping instrument is used, it is necessary to perform centering and leveling in order to improve the measurement accuracy. Usually, the staff directly erects the surveying and mapping instrument on the top of the bracket, and then uses the centering rod for centering and leveling.
