“…Generally, principle of measurement can be categorized into 3 approaches, i.e. orientation (angular), position (distance) and hybrid (combination of both orientation and position measurement) (Cuypers et al, 2009;Li et al, 2014) as per Fig. 1.…”

“…0.5 arcsec (Leica;2016). The advantages include capability in large working volume, high resolution measurement and immune to electromagnetic interferences (Li et al, 2014). On multiple angles measurement, more than 2 theodolites are required to aim at each other mutually and collimate with the mirror cubes on the measured article.…”

In a satellite development cycle, alignment measurement is crucial especially during assembly and integration of satellite part and component as well as a series of mechanical tests performed onto it. It plays a vital role in ensuring critical components of satellite such as antenna, solar panels and reaction wheels are correctly and precisely aligned as per design specifications. Besides, it serves as complimentary analyses for pre and post inspection and verification during mechanical tests. Combination of two measurement parameters, namely the orientation (angle) and the position (distance) will provide complete coordinate knowledge of satellite system. Selection of appropriate measurement technique and equipment on large scale measurement play significant factor in determining the whole measurement plan. Further analyses of measured data will be performed on metrology software, Spatial Analyzer. Details on technique used for satellite alignment measurement are elaborated. A measurement model and real measurement data emphasizing on effectiveness of the mentioned technique are presented.

Abstract. The critical analysis of the self-centering devices for inner cylindrical surfaces highlights a number of advantages and disadvantages of these solutions. The key benefit is the precision but the most important disadvantage it is that doesn't covers a sufficiently range of values for the inner diameters and are very complex. In the present paper a solution of centering mechanism with calibrated rollers that eliminates the disadvantages mentioned above, with a medium complexity but ensuring a sufficient range of values for measured surfaces is proposed. The method used to obtain the specified range of values is graphic method.

Pose measurement and assembly of spacecraft components based on assembly features and a consistent coordinate system

To assemble spacecraft automatically and precisely, it is vital to measure the relative spatial pose (position and orientation) of the assembly features of the spacecraft components before assembly. For large-scale spacecraft components, the global measurement method is mainly utilized to guide assembly control, and its accuracy and efficiency have ultimately failed to meet requirements. To address this issue, a novel measurement method is proposed. Since the goal is to measure the relative spatial pose of the assembly features of the spacecraft components, the proposed method measures it directly to ensure the consistency of the measurement and assembly coordinate system. This method has the advantage of high precision because it can reduce the influence of structural parameter errors and is not limited by the scale of the spacecraft components.In addition, it requires only one offline calibration, which significantly improves the efficiency of online measurement and assembly. Taking the control moment gyroscope (CMG) assembly task as an example, a measurement system and its corresponding calibration device are designed and developed. After calibration by the calibration device, the measurement system is mounted on the assembly features of the CMG to measure the relative spatial pose between the assembly features of the CMG and the assembly features of the mounted base (MB). Finally, six assembly experiments are completed according to the measurement results. The experimental results show that this method has high accuracy and can guide the robot to achieve high assembly accuracy, satisfying the assembly requirements of typical spacecraft components.
