激光陀螺惯性导航系统静态校准方法的研究

Research on the Static Calibration Method for a Laser Inertial Navigation Syetem

介绍了激光陀螺惯性导航系统（ＬＩＮＳ）的误差模型，研究了一种多位置的静态校准方法，通过旋转一个位置分离一个主要变量的方法，逐次分离出加速度计和陀螺的零偏、标度因数误差及不正交角共２０项误差系数并加以补偿。实验研究表明，本方法的校准精度较高，而且时间较短。

In this paper a method of static calibration for a laser inertial navigation system (LINS) is investigated based on the analysis of its error model.Twenty error coefficients are estimated and compensated sequentially including the accelerometer and gyro biases , scale factor errors and misalignment angles after each rotation of the LINS .As shown by the experimental results ,this method of calibration is simple in calculation and accurate in error compensation with short calibration time.
