空空导弹捷联惯导系统空中标定技术研究

针对空空导弹捷联惯导系统提出了一种空中标定方法。该方法是在载机空中飞行的过程中,利用机载主惯导到弹载子惯导的数据传递过程,利用卡尔曼滤波估计算出惯性器件误差的一种标定方法。通过数字仿真分析,该方法可以实现对陀螺常值漂移和加速度计常值偏置一定程度的标定,并能够延长其定期标定的周期。

Research on In-flight Calibration Method of SINS on Air-to-air Missile

In this paper,an in-flight calibration method for the SINS（Strapdown Inertial Navigation Syetem） on AAM（air-to-air missile） is studied.It uses Kalman filter to estimate the errors to be calibrated in the data transfer process from the airborne master inertial navigation sys-tem to the missile slaver inertial navigation system.This method can calibrate the gyro constant error and the accelerater constant error by simula-ting.It prolong the periods of the constant calibration.
