摘要
介绍了倾斜补偿下三轴磁航向测量的基本原理,分析了航向误差的形成原因。根据罗差分解和正交修正基准轴的概念,本文提出了一种基于二次正交修正的高精度磁航向误差补偿算法,该方法具有补偿精度高,算法简单等优点。文章给出了该算法应用于HMR2300型磁罗盘进行航向测量的实验结果,说明了该算法的可行性和有效性。
In the paper, the theory of three-axis magnetic heading measurement with tilting compensation is introduced, and the cause of heading error is analyzed. Furthermore, a high-accuracy algorithm of heading error compensation is presented, which is based on the compass deviation decomposition and the datum axis of orthogonal correction. The method introduced in this paper is of high accuracy and simple formulae. The experiment results of HMR2300 also show its feasibility and validity.
