陀螺仪随机漂移的测量及其数学模型的建立

Measurement of Random Gyro Drift and Establishment of Mathematical Model

为提高惯导系统的精度 ,对影响陀螺仪精度的重要误差源———陀螺仪随机漂移进行了研究。在统计分析的基础上采用固定方位力矩反馈法测量陀螺仪的随机漂移 。

To improve the accuracy of strap down inertial system, the gyroscopic drift that is the major error source to affect the accuracy of gyro is studied in this paper. On the basis of statistic analysis,the fixed azimuth moment feeding is adopted to measure random drift of gyro, and the mathematical model is established by stabilization time method.
