Gao Huibin. A New Progress on Tracking Precision of Gear-driving Theodolite[J]. Editorial Office of Optics and Precision Engineering, 1997,(5): 53-56DOI:
This paper introduces a system which can solve the special problem of gear-driving system
and it makes the tracking precision of theodolite using gear drive come up to the level of that using moment motor drive.This system was used in a theodolite remaking task successfully.
