A computer model of autocollimator, based on description of object rotations by the quaternionic method, is considered. The effects of main primary errors of autocollimation angular measuring system on the measurement error of the position axis and magnitude of object rotation are analyzed. Comparison of autocollimation measuring algorithms based on quaternionic and matrix models is carried out using the criterion of the influence of deviations of autocollimator parameters on the total measurement uncertainty.
