| 摘 要： | 误差标定及补偿是提高惯性系统使用精度的重要手段。惯导系统原位标定在提高装备机动性和保障效率方面具有明显的优势。综合考虑惯导系统的框架轴、陀螺和加速度计安装误差,详细推导了适合惯导系统原位标定的误差模型。给出了一种16位置标定方案,分离出惯导系统的36项误差系数。经仿真验证,标定精度取得了良好的效果。

| Abstract: | Error calibration and compensation is an important means for increasing the practical precision of inertial systems.The advantage of in-situ calibration in the aspects of raising equipment flexibility and guarantee efficiency is obvious.The error model suit for in-situ calibration is derived when the mounting errors for the frame,gyro and accelerometer are considered.A 16 position calibration scheme is given,which may segregate 36 error factors,and the simulation result shows that the calibration precision is good. |
