DS39-0101-1型陀螺仪采用框架式陀螺系统,在实际工作中,由于受多种因素的影响,陀螺转子在其旋转轴上存在漂移现象,影响方位测量的精度。分析了漂移产生的原因,叙述了对该仪器的检查方法和检查时应注意的事项,着重阐述了陀螺仪漂移校正的数学方法,对不变漂移率法、可变漂移率法和最小二乘线性拟合法3种校正方法进行了讨论,结果符合实际测量值。
DS39-0101-1 gyroscope using frame-type gyroscope system, in practice, due to a variety of factors, the gyro rotor drift in the axis of rotation, the impact of azimuth measurement accuracy. The causes of drift are analyzed. The inspection methods of the instrument and the items to be noticed during inspection are described. The mathematics method of drift correction of gyroscope is emphatically described. The methods of constant drift rate, variable drift rate and least squares Three methods of linear fitting are discussed, and the results are in line with the actual measured values.
