| Abstract: | For achieving large-scale space photoelectric tracking, the axis error of the new three-axis gimbal with collimation axis eccentricity was studied. By means of the attitude transformation and based on geostatics, the new photoelectric theodolite was analyzed, and then a specific calculation method for pointing precision was given out. Thereby the new precision arithmetic and error distribution of the three-error axis of photoelectric theodolite with collimation eccentricity were searched. Through the material gimbal pointing precision calculation, the perpendicularity error among axis errors have the most effect on pointing error and the new calculation method of pointing precision is effective. |
