摘要

研究了利用扩展比例因子模型提高振动陀螺标度因子温度误差在导航设备中的标定精度的问题。在常规温度多项式模型的基础上，增加了振动频率、驱动幅值和正交幅值等可测参数。此外，在已知恒角速度旋转陀螺时，测量了陀螺在工作温度范围内的温度变化过程中的比例因子。估计了宽温度范围内标度因子温度误差校准。

Vibratory gyroscope scale factor multi-parametric calibration

The problem of vibratory gyro scale factor temperature error calibration accuracy increasing using expanded scale factor model to use in navigation devices is considered in this work. The conventional temperature polynomial model is complemented by additional measurable parameters such as vibration frequency, drive amplitude and quadrature amplitude. Besides, scale factor is measured during temperature change within working temperature range when rotating gyro with known constant angle rate. Scale factor temperature error calibration in wide temperature range is estimated.
