摘要
在捷联惯导技术应用到石油采掘与矿井勘探领域的背景下,探讨如何使用低精度的惯性传感器获得精确的初始姿态信息。本文借鉴陀螺寻北仪的两位置寻北方案,研究了基于寻北技术的初始对准方法,利用该方法可滤除惯性传感器的常值漂移。仿真表明在使用低精度的惯性传感器条件下,利用该方法能获得较高精度的初始姿态信息。
In the context of applying the SINS technology to mine the exploration field, this paper studies how to obtain the accurate attitude information in initial alignment using inertial sensors with low accuracy. This paper refers to the two - position the north seeking means, and studies the means of initial alignment based on the north seeking technology. The constant drift can be deleted by this method. Though under a low accuracy of the inertial sensors, we can use this method to obtain high-accurate initial attitude information, as the simulation shows.
