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； - Initial alignment is one of the key technology of inertial navigation system . it directly influence the navigation performance of navigation system . because some random factors exist in the system , there are some difference between the precision of initial alignment and alignment time
初始对准是惯性导航系统的关键技术之一，它直接影响惯导系统的导航性能，由于系统中存在有各种随机因素，初始对准的精度和对准时间之间存在着矛盾，对准精度越高所需时间也越长。 - The system error is mainly determined by sensor error and initial alignment error by analyzing the error transfer characteristic of the sins system . after compensating the sensor error , the precision of the whole system almost remains the initial alignment process . it should include of gyroscope and speedmeter to compensate the error
通过对sins系统的误差传播特性分析可以发现，系统的误差主要由传感器误差和初始对准误差决定，在对传感器误差进行补偿之后，整个系统的精度几乎就保持在初始对准的精度上；另外，在初始对准过程中还包含陀螺和加速度计的测漂和定标工作，以便进行误差补偿。 - 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
