| 英文摘要 | The error sources that cause the pointing error are briefly analyzed to check whether the spatial static pointing error of a newly developed optical testing target satisfies the design index of 5', and a pointing error model of target mechanism is established by the homogeneous coordinate transformation method. The azimuth and elevation errors of target are calibrated using Leica total station with high precision, and the pointing error of target is further synthesized. The calibrated results reveal that the maximum spatial static pointing error, max, is 275", the mean value, , is 165.9", and the square root, , is 71.5". In order to further improve the pointing accuracy of target, the least square method is used to fit the coefficients in the error model based on the calibrated data samples, and the calculated error models are used as the correction models of azimuth and elevation errors. When the pointing errors are corrected by using the proposed models, the average pointing error values of target mechanism at calibration points and the specific orbit are 21.1" and 20.9", respectively, and the root mean square are 10.6" and 7.2", respectively, which indicates that the static pointing error of the new target is greatly improved after error correction. 2019, Editorial Board of Acta Armamentarii.
