摘要：

The mirror repositioning system is one critical system in large-size deployable space telescopes that aids in correcting errors in mirror orientation once deployed. Stewart mechanism is employed for reorienting the mirror due to its potential for use in high-precision applications, and a high-range and high-accuracy Stewart platform for positioning the mirror was designed using dual-resolution actuators. System characterization is crucial for understanding, optimizing, and evaluating the performance of a system. It provides insight into a system's behavior, strengths, weaknesses, and limitations, aiding in troubleshooting, design decisions, and quality assurance. Overall, it forms the foundation for ensuring the functionality, efficiency, and reliability of a system throughout its lifecycle. We discuss the techniques adopted for characterizing the mirror repositioning system and the methods employed for error reduction in the system.
