摘要
分析了车载试验时平台的安装方式以及所需要的外测信号等问题,给出了误差模型以及导航误差方程,设计并进行相关软件仿真。结果表明,在现有外测信号精度下,该方法可分离出惯导平台误差中加速度计和陀螺仪的零次项误差系数,对加速度计的一次项误差系数分离效果也较好。
How to fixing the platform in the vehicle and what exterior information used is analyzed, and the inertial navigation platform error model and navigation error equation is given, and also the Kalman filter is designed and used to simulation. The simulation results show that in the art of the exterior information precision this method can separate the bias of the gyro and accelerometer; and the scale factor error of the accelerometer is also separated, the result is satisfactory.
