The method of repetition of horizontal angle measurement helps in eliminating systematic errors such as those due to eccentricity of verniers, wrong adjustment of line of collimation and trunnion axis, and inaccurate graduation. However, it does not eliminate errors due to displacement of station signals, as these are random errors caused by external factors and not by the instrument's systematic errors.
