摘要

本文报道了具有超导航级性能的小型化科里奥利振动陀螺仪(CVG)发展的两个新的里程碑。首先，基于大大简化的生产单元，展示了小尺寸和低零件数的毫微米半球形谐振陀螺仪(mHRG)，测量了0.00025°/rt-hr的ARW和0.005°/hr的偏差。其次，使用双mHRG系统进行实时自校准验证，在数天时间和温度下实现0.001度/小时的战略等级稳定性。我们相信这项工作的结果为追求下一代CVG架构、设计和自校准的惯性和MEMS社区提供了有价值的最新参考。

Toward software defined coriolis vibratory gyroscopes with dynamic self-calibration

This paper reports two new milestones in the development of miniaturized Coriolis Vibratory Gyroscopes (CVG) with beyond navigation grade performance. Firstly, a small size and low parts count milli-Hemispherical Resonator Gyroscope (mHRG) based on a drastically simplified production unit is demonstrated with measured 0.00025 deg/rt-hr ARW and 0.005 deg/hr bias. Secondly, real-time self-calibration is validated using a dual mHRG system achieving strategic grade stability of 0.001 deg/hr over days of time and over temperature. We believe results of this work provide a valuable state of the art reference to both the inertial and MEMS communities pursuing next generation CVG architectures, designs, and self-calibration.
