| 摘 要： | 在考虑框架轴、陀螺和加速度表安装误差的备件下，推导了惯性平台陀螺仪和加速度表的通用输出误差模型。为分离陀螺仪误差系数、加速度表误差系数、陀螺仪安装误差、加速度表安装误差，设计了一个16位置的标定方案，以完整地分离出惯性平台的42项误差系数。算例表明，采用该方法标定，陀螺误差系数的精度可优于5％，加速度表则更高。

| Abstract: | The general module of output error for gyro and aecelerometer on the platform was derived when the mounting errors for the frame, gym and accelerometer were considered in this paper. To separate the error factor and mounting error for gym and accelerometer re~spectivdy, a 16 position calibration scheme was given, which would segregate 42 factors. The calibration for an example showed that the error factor of gym gained by this method was better than 3 %, and the calibration of accelemmeter was much better even. |
