摘　　要：针对某水下运载器中罗盘的工作状态,提出了适合于水下工作的电子罗盘的误差补偿方法。通过分析误差产生的原因,结合实际情况,提出将补偿区间分段的方法,在各个区间分别进行最小二乘误差补偿。实验结果表明:采用分段补偿的方法可以有效补偿小区间误差,能够将最大误差降低到0.3°之内,提高其磁航角的精度,满足高精度导航系统要求。Based on the manipulating position of the electronic compass in some underwater vehicle, an error compensation method for electronic compass is proposed, which is fit for working under water. Considering the detail,segmented interzone compensation is proposed by analyzing the reason of the error, which least squared method is adopted in the error compensation in every interzone. The experimental result shows that the segmented error compensation can compensate the error of the small interzone effectively, the maximum error drops to 0.3° even better and the accuracy of the magnetism heading is improved. It can meet the demand of a navigation system with high-accuracy.
