The invention discloses a system for measuring final-assembly high-precision angle of a spacecraft, which comprises a plane mirror, a charge coupled device (CCD) photoelectric collimating device, a precise guide rail, a precise rotary table, an adapter and an electromechanical control part, wherein the plane mirror, the CCD photoelectric collimating device and the precise guide rail are erected at the front of the precise rotary table by 1m, the plane mirror is perpendicular to the axial direction of the precise guide rail, the rotatable precise rotary table is provided with the adapter supporting the spacecraft to be measured, and the electromechanical control part controls the rotation of the precise rotary table and the movement of the precise guide rail to automatically receive angle data obtained by the means that the CCD photoelectric collimating device receives a returned collimating light beam by a CCD, and a division value read according to a circular dividing table and rotation angle data of the precise rotary table, to compute angle of an assembly part on the spacecraft to the spacecraft. Compared with the prior art, after the system for measuring the final-assembly high-precision angle of the spacecraft is used, the collimating observation precision and stability can be improved, an error propagation accumulation link can be reduced, and the measurement efficiency can be improved.
Description
technical field [0001] The invention belongs to the technical field of angle measurement, and in particular, the invention relates to a device for measuring the angle posture of assembled equipment relative to a spacecraft or other equipment during the assembly process of a spacecraft. Background technique [0002] During the final assembly of the spacecraft, the coordinate system formed by the normal of the reflective surface of the optical cube mirror on the installed equipment represents the angular attitude of the equipment. The attitude of the measuring device actually measures the angle between the normals of the reflective surfaces of the cube mirror. At present, the method of building a station with a theodolite is widely used in China. Use multiple high-precision electronic theodolites, such as T3000 and TM5 100A of LEICA Company, etc., set up multiple theodolites to be self-aligned with the mirror surface to be measured, use one of the electronic theodolites to es...
