Abstract :
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.
