摘要: 为了解决在城市交通中动态干扰磁场对磁罗盘的干扰问题,对磁罗盘动态干扰的特点进行了分析;提出了差分磁罗盘DMC(Differential Magnetic Compasses)的概念;设计了基于差分磁罗盘和速率陀螺的组合航向实验系统;研究了基于阈值判断的差分磁罗盘动态干扰识别技术.实地跑车实验结果和理论分析吻合较好.实验表明:与单一磁罗盘相比,差分磁罗盘能较好地识别出动态磁场干扰,提高了磁罗盘在城市交通中的可用性.组合航向系统的鲁棒性和精度也得到了提高.

Abstract: To solve the magnetic compass interference problem caused by the dynamic interference magnetic field in urban traffic environment, the feature of the dynamic magnetic interference was analyzed. And the concept of the differential magnetic compasses(DMC) was proposed. An integrated heading system module based on the DMC and the rate gyroscope was designed. The dynamic interference recognition technology of DMC based on the judgment of the threshold value was investigated. The agreement of the theoretical analysis with the real navigation experimental results shows that the DMC can recognize the dynamic magnetic interferences better, compared with single compass. The application range of the magnetic compass in the urban traffic environment is extended. The robust and the precision of the integrated heading system are also improved.
