摘　　要：介绍以磁阻罗盘HMR3000和微处理器为基础的数字磁罗经系统的硬件组成、软件设计原理及其在船只导航中的应用。该系统可以自动消除自差,以便于避免船只导航中繁琐的自差修正,同时增强航向的准确度,减少海事事故的发生,系统可以实现导航数据的精确、实时测量,对航行方向可以设置预警功能,及高清晰显示航向数据。The hardware structure and the software designing principle of the digital magnetic compass system based on the magnetoresistive compass HMR3000 and microcontroller and its application in the navigation of ship are expounded. The system can automatically eliminate autodyne, in order to avoid fussy autodyne correction in navigation, and at the same time to enhance accuracy of the navigation, and to decrease maritime accident. The system can achieve accurate and real-time measurement for navigation data, and can set advance alarm of heading, and clearly display heading data.
