This book systematically explores the topic of "Space Coilable Mast" in spacecraft mechanisms, addressing practical challenges, summarizing advancements, and proposing original theories and technologies. It adopts a structured approach of "Introduction - Key Technology - In-Orbit Verification and Application" to provide a comprehensive discussion that promotes the technological development of China's spacecraft mechanisms. In the "Introduction," it reviews the evolution and applications of space deployable structures, analyzing the prospects and key technologies of space coilable masts. The "Key Technology" section addresses challenges like unclear development laws and complex modeling, presenting breakthroughs in low-disturbance deployment, high-precision pointing, and integrated design and testing. Finally, the "In-Orbit Verification and Application" chapter highlights practical insights gained through missions such as APSCO SSS and CATCH, enhancing understanding of the mast's critical technologies.
