Abstract Aiming at the requirement of high precision, high orbit and long-life in tasks of spacecraft, photonic crystal fiber (PCF) is used in the development of Interferometric Fiber Optic Gyroscope (IFOG). And in this paper, we introduced current work in development of this filed, of which the bias stability is 0.001°/h and operating range is ±20°/s. In addition, the technology included PCF used in our work has been launched in SJ-20 on December 27, 2019 successfully. And On orbit data show that all indexes meet the design requirements and can meet the application requirements of spacecraft in the future.

高精度光子晶体光纤陀螺结果与飞行试验

摘要 针对航天器任务对高精度、高轨道和长寿命的要求，光子晶体光纤（PCF）被用于干涉光纤陀螺仪（IFOG）的研制。在本文中，我们介绍了该领域目前的发展工作，其中偏置稳定性为0.001°/h，工作范围为±20°/s。此外，我们工作中使用的包括PCF在内的技术已于2019年12月27日在SJ-20上成功发射。并且在轨数据显示，各项指标均满足设计要求，可以满足未来航天器的应用需求。
