摘要: 本文提出一种基于Coriolis效应的非陀螺找北系统实现方案,利用旋转线加速度计来敏感地球速率的水平分量,实现找北过程。文中建立了该系统的基本力学模型,并对其主要机械误差进行了理论分析。

Abstract: This paper presents a scheme of a Coriolis effect based nongyroscopic north seeking sys?tem. The scheme completes the north seeking process by sensing the horizontal component of the earth’s spin rate with a rotating linear accelerometer. Besides an introduction to the basic mathemati?cal model of such a nongyroscopic north seeking system, a theoretical analysis is given to deal with the main mechanical errors of the system.

Key words: north seeking system , Coriolis effect , accelerometer
