Abstract：In order to research surveying precision of similar material simulation experiment measured by reflector plate pattern,according to measurement practice of similar material model error propagation law,theoretical magnitudes of point site coordinates precision were calculated. According to field test,based on Bursa theoretical model,point coordinates within surveying coordinate system were transferred automatically to local coordinate system utilizing the software Matlab. The transferred coordinates were analyzed and contrasted with the results obtained by digital close-range photogrammetry. The studies show that theoretical mean error extreme value of points coordinate is ± 1. 5mm along X coordinate axial direction based on total station instrument reflector plate pattern,and ± 1. 06 mm along X and Y coordinate axial direction respectively. When vertical angle and horizontal angle are controlled from-π /4 to π /4,mean error of point site coordinates can be controlled within sub millimeter. Comparing with digital close-range photogrammetry results,actual mean error of point site measurement is 0. 43 mm and 0. 37 mm along X and Y coordinate axial direction respectively through the pattern of total station instrument reflector plate.
