Abstract To accurately measure large size poses, a large size pose measurement device consisting of 7 laser tracking interferometers is established. According to the difference in the number of laser tracking interferometers measuring each mirror, the effects of two tracking methods, 322 and 331, on the accuracy of pose measurement are simulated. Therefore, it is found that the position of the measured point is related to the distance of the base station plane. The error model between the relative position between the measured point coordinate value and the measurement base station and the measurement error is derived from the coordinate solution formula. By analyzing the sensitivity of errors in the directions of x, y, and z to distance changes, it is found that errors caused by distance changes in the z direction are the most sensitive. When the distance between the measured point and the measurement base station is reduced from 1300.8mm to 0mm, the measurement error increases from 2.2μm to 2626.1μm. The actual attitude measurement experiment results show when a tracking method is adopted, the measured point can be avoided from being too close to the plane of the station, which is helpful to improve the measurement accuracy of the system.
