解釋
零點漂移-
In the end, null shift and scale factor of the newly developed mdrlg is tested. random walk of the gyroscope is 0. 0163 ?, rms of drift is less than 0. 09 ? h, relative precision of scale factor is better than 10 ppm
最後對新研製的機抖陀螺進行了漂移和比例因子測試,實驗測得陀螺隨機游動系數為0 . 0163 / h ~ ( 1 / 2 ) ,漂移均方差小於0 . 09 / h ,比例因子相對精度優於10ppm 。
