| 摘 要： | 惯性器件标定一般都必须对北和调平,以消除地速及重力加速度的影响,但是不适合在靶场及其他野外环境下采用.根据激光捷联惯导系统的误差方程,在激光捷联惯性组合不指北、不调平情况下,通过十位置的标定方法,抵消掉地速及重力加速度的影响,从而得出加速度计的误差系数和陀螺的零偏.最后对实验精度进行了论证,认为此方法可以满足激光陀螺捷联系统的性能要求.本方案利用最少的测试位置,得到了所有需要的信息,利用率高.

| Abstract: | During the calibration of inertial devices,the north-seeking and the level-adjusting must be performed to eliminate the influence of the ground velocity and the acceleration of gravity,but it is not adaptable in the environment of range and other field.According to the error equation for laser gyro strapdown inertial navigation system,when there are no north-seeking and level-adjusting,the influence of the ground velocity and acceleration of gravity are counteracted by 10 position calibration,the error parameters of accelerometer and the calibration factors of laser gyro are gained.Finally,the accuracy of the experiment are discussed.The method is believed to meet the performance requirements of laser gyro strapdown system.In this scheme,the least measurement position is required and the most information is gained.The utilization ratio of this method is high. |
