陀螺的随机漂移与测试方法的研究

On the Random Gyro Drift and Test

本文利用试验数据对陀螺的随机漂移进行了分析,指出陀螺的随机漂移实际上有两种:陀螺噪声和漂移测试数据隔日相减所得的随机漂移。本文指出,用力反馈法测得的随机漂移主要是陀螺噪声,而伺服法测得的才是正规定义下的随机漂移。本中还简要分析了伺服数据处理中的动平均时间的选择。

In this paper the random gyro drift is analyzed ba- sed on the test data.It is pointed out that there are two kinds of random drift:one is the gyro noise and the other is the random component obtained by subtracting the results of one day's drift testing from the results of the previous day's testing.It is pointed out in this paper,that the random drift obtained by torque-res traint test is mainly the gyro noise.And the random drift from the servo test is the random drift which this terminology really means. The choice of the averaged time interval in servo-test data process- ing is also discussed briefly in this paper,
