| 摘 要： | 研究了车载筒装导弹状态下捷联惯性导航系统加速度计误差系数标定问题。首先对加速度计进行了误差分析,在此基础上推导了误差模型,提出了以车的机动作为激励方式,设计了一种不开箱标定方法。仿真结果表明,该误差模型正确且标定方法能够对误差进行补偿,从而提高导航精度。

| Abstract: | In this paper,the problem of calibrating the error coefficient of accelerometer in strapdown inertial navigation system under the state of vehicle missile-in-container.The error model was deduced based on analyzing error of accelerometer.A calibration method was designed without opening the box by the way of vehicle movement as actuator mode.The simulations show that the error model is correct and the calibration can compensate the error and improve the precision of navigation. |
