| 摘 要： | 对于给定的传递对准的误差模型，针对常值外观测速度、位置误差和随机外观测速、位置度误差两种情况，分别对惯导系统的传递对准误差模型的解算偏差和Kalman滤波器的估计偏差进行了仿真分析。结果表明，外观测误差引起的INS传递对准的估计偏差不能忽视，为采用更优的估计方法提供了依据。

| Abstract: | The solution error and the Kalman filter estimation bias are simulated respectively using the given transfer alignment model for two cases, i.e. constant and random external velocity and position detection error. The analysis results indicate that the estimation bias resulted from the external detection error cannot be neglected for the INS transfer alignment and may be taken as the basis for applying better estimation methods. |

| Keywords: | transfer alignment Kalman filter estimation bias solution error |
