摘　　要：以电子罗盘在某型便携式方位伺服转台中的应用为背景,分析了电子罗盘测向精度误差主要来源,开展了罗盘倾斜误差补偿、罗差补偿及磁偏角误差补偿方法的研究,并结合项目实例进行了倾斜实验、24位置罗差标定补偿实验及我国境内达170个城市的磁偏角误差补偿实验。实验结果表明,该文所研究的补偿方法是简单、有效、可行的,其北向精度可修正到1°范围内,非常适用于车辆、无人机等对方位精度有一定要求,同时对系统外形尺寸有较严格限制的场合。The main factors leaded to the direction-finding error of the revolving platform were analyzed based on the application of the electronic compass to the portable azimuth servo revolving platform. The compass inclination error compensation method,the environment error compensation and the magnetic declination error compensation method have been investigated in this paper. The inclination experiment,the 24-position environment error cali- bration compensation experiment and the magnetic declination error compensation experiment in 170 cities of China have been carried out combined with the actual application example. The results showed that the error compensation method proposed in this paper had the features of simplicity, effectiveness and feasibility, and the north--direction accuracy could be corrected to within l^range,thus was particularly suitable for the applications to those cases of the special requirements for the azimuth accuracy such as the vehicles and the unpiloted plane etc. , and those cases of the strict requirements for the external dimensions of the systems.
