摘要
提出了一种高精度电子罗盘设计方案.完成了硬件电路设计,给出了主要软件的设计思路.电子罗盘以DSP为核心处理器,采用磁阻传感器敏感地磁场三维分量、微惯性测量单元实现载体姿态和地磁扰动补偿,实现了载体磁方位的高精度测量.设计了本机数据显示和以太网接口,既可以作为个人导航设备,也可作为导航系统的一个节点.
A high precise electronic compass scheme was proposed.The hardware circuit design was completed and the ideas of software were given.The digital signal processor（DSP） was selected as core processor and the magneto resistive sensor to sense the 3D components of geomagnetic field,and the micro inertial measurement unit was combined to compensate the attitude of vehicle and geomagnetic field disturbance for high precise azimuth measurement.Additionally,local LCD interface and ethernet interface were designed,which could be used not only as a personal navigation equipment but also as a data node of navigation system.
