“…The first linear guide LLISI in China that was developed by our institution is shown in Figure 1b. The length of the linear guide was about 57 m, and the two guides were placed on a granite bearing platform, with a distance of about 600 mm and an approximate height of 1.3 m. The laser tracker was aimed at the optical target mirror [17] on the LLISI, which was fixed on the platform via magnetic force. According to the loading conditions, the bearing platform was controlled to move forward, and the coordinates in the coordinate system of the laser tracker were recorded.…”

The large length indoor standard installation (LLISI) serves as a standard traceability system for large-scale measuring devices, and hence evaluating the accuracy of its measurements during motion is of great importance. A laser tracker, as a single-point scanning method with strong anti-interference ability and high accuracy for 3D measurement, can meet the measurement requirements of LLISI. In this study, a laser tracker was used to evaluate the accuracy of LLISI during motion based on the single-point scanning method. Fifteen measurement combinations including five measurement intervals and three measurement speeds were selected in the experiment and the results were compared with the measurement data of a laser interferometer. By analyzing the local movement speed of the ISS platform, the uncertainty in local measurement speed of the platform was evaluated. The results showed that the laser tracker has high measurement accuracy and good repeatability for the measurement of LLISI, which can provide strong support for data resource protection of LLISI.
