Based on assembly features and a consistent coordinate system, pose measurement and spacecraft component assembly are performed

Author(s): Lily Zheng

 It is essential to measure the relative spatial pose (position and orientation) of the assembly features of the spacecraft components prior to assembly in order to assemble spacecraft automatically and correctly. The global measuring approach is primarily used to direct assembly control for big spaceship components, however its accuracy and effectiveness have eventually fallen short of expectations. An innovative measurement technique is suggested to deal with this problem. The suggested approach measures it directly to ensure the compatibility of the measurement and assembly coordinate systems since the objective is to measure the relative spatial posture of the assembly features of the spacecraft components. Because it may lessen the impact of structural parameter mistakes and is not constrained by the size of the spacecraft components, this technique has the advantage of high precision.
