摘要
论文针对电子罗盘在小型多旋翼无人机上这一特殊使用背景,自行设计了一种基于ARM处理器的三轴电子罗盘。论文中介绍了电子罗盘的硬件设计方案与软件设计流程。同时对电子罗盘的"椭球假设理论"进行了简易证明,在进行零位粗校准后采用该理论对所设计的电子罗盘进行自精校准。实验表明所设计的电子罗盘在进行校准后精度约为1°,达到设计要求。
An ARM CPU 3-axis electronic compass is designed for using in small multi-rotors unmanned vehicle.The hardware design and software design of electric compass is introduced in the paper.The ellipsoid assumption compensation is simply proved and used in the 3-axis electric compass after zero-bias adjustment.The experiment indicates the compass’precision is nearly 1degree,arrived at the design requirement.
