摘要
近年来,电子指南针被广泛的运用于导航设备中。本文首先介绍了电子指南针工作的原理和实现方案,然后深入分析了误差中对指南针精度影响较大的倾斜误差,并针对该误差提出了一种合理的解决方案。最后文章对电子指南针系统中的各种误差做了小结,并提出了一种平滑滤波算法来消除误差的影响。实践证明该方案极大地提高了系统的稳定性和精度。
The electronic compass is widely used in the navigation equipments recently.The paper introduces the theory and implementation of the electronic com- pass,especially focusing on the error and calibration.The paper also mentions a kind of arithmetic of weight aver- age for the stability of the electronic compass.Tilt error is thoroughly analyzed,and a method for compensation is proposed in order to promote the stability and accura- cy.
