Abstract: The long term storage life analysis and practical work of Chang’e-6 fiber optic gyro inertial measurement unit are carried out. The factors affecting the storage life of the fiber optic gyro inertial measurement unit are identified, and a set of multi-source information fusion life analysis method based on natural storage test is proposed. The results of Chang’e-6 flight test show that the storage life analysis method and storage measures adopted are effective, and can be used as auxiliary means for subsequent storage reliability evaluation and engineering evaluation of fiber optic gyro inertial measurement device.

Key words: fiber optic gyro inertial measurement device, long term storage, life influence analysis
