Iteration algorithm of calibrating initial attitude and instrument ' s errors for sins 捷联惯导系统初始姿态和仪表误差标定迭代算法研究
Study on strapdown inertial navigation system ( sins ) the concept , process and the already done work of initial alignment of sins arc introduced briefly . for selecting coordinate and deriving the error model , presenting some kinds of coordinate in the inertial navigation system ( ins ) ; the initial alignment of sins theory is introduced in detail ; the linear error model of moving base initial alignment of sins is derived , including analysis in characteristic and influence of system error of inertial apparatus . 捷联惯导系统的研究:首先概要介绍了惯导系统的相关知识,阐述了捷联惯导系统的优点;分析了初始对准姿态确定的几种坐标系,为建模定义了坐标系选择和姿态矩阵;详细研究了捷联惯导系统的初始对准原理,推导并给出了捷联惯导系统动基座初始对准的误差方程,并分析了误差特性以及惯性仪表误差对系统误差的影响;
Different filtering methods have been tested to examine the effects of all kinds of filters . the correction of inertial sensor errors , navigation algorithm , coning motion , and sculling motion have also been investigated . based on the above works , the initial alignment on stationary base using imu with mdrlg has been carried out , and an usable navigation software has been completed 对机抖激光陀螺引起的高频振动的补偿方法进行了研究,对不同的滤波方法进行了试验;对机抖激光陀螺捷联系统的仪表误差补偿、导航解算算法、圆锥补偿算法和划桨效应补偿方法进行了研究;对静基座条件下机抖激光陀螺捷联惯导系统的初始对准方法进行了研究,编写了实用的导航软件。
