| 摘 要： | 提出了一种引入数值拟合计算的速率陀螺系统校准算法.此算法主要是在陀螺定参系统中,通过回归建模计算来确定陀螺刻度因数以及各漂移系数的大小.它考虑了在工程应用中,陀螺本身的特性以及在生产过程中的机械加工和装配精度等因素对系统带来的影响,从整体出发来校准速率陀螺系统参数,使得系统测试方位角的波动范围有了进一步的缩小.

| Abstract: | This paper proposed a correction algorithm for a rate gyroscope system,which introduced the calculation using values fitting.In the Gyro Parameters Deciding System,this algorithm mainly was used to determine the gyro scale factors and the drift coefficient sizes through the calculations with regressive model.It had considered the influence of some factors such as the instrument's own characteristics,the machine finishing and assembly precision in production.In order to calibrate the gyroscope system parameter,this algorithm looked the gyro's character and the machine precision as a unit.By this way, the fluctuant extension of azimuth angle had been gotten less. |
