| 摘 要： | 传统的惯性平台的标定方法存在很大的局限性.根据高精度惯性仪表的特性,对传统的误差模型适当地进行了简化,建立了供自标定使用的陀螺仪、加速度计误差模型;针对三框架四轴全姿态惯性平台,提出了一种七位置自标定方案;给出了公式解算方法及数据测试方法,占用时间约40 min,共分离出包括两个水平地速分量在内的20项误差系数.通过自标定时间、精度分析,表明该自标定方案有助于缩短平台的测试时间,提高武器系统的使用精度.

| Abstract: | The traditional calibration method for inertial platform has much localization.According to the characteristic of high precision inertial instrument,the traditional error models is simplified and the ones for gyroscope and accelerometer in self-calibration is established.A scheme of 7-position self-calibration for 3-frame 4-axis all-attitude inertial platform is put forward.Some formulas and test methods are given.It will take about 40 minutes to calibrate 20 errors in all,including two aclinic earth self-r... |
