摘　　要：无人机、车载导航等方面需要用到地磁定向,而电子罗盘在应用中起到关键作用。针对车载导航的姿态控制和导航精度,本文以PNI公司磁感传感器为基础,结合MEMS加速度传感器、温度传感器及处理器MSP430F1611等器件构建一个具有倾角补偿的电子罗盘。实验结果表明,该电子罗盘具有体积小、重量轻、功耗低和精度高等特点。通过实验验证了该方案的可行性与有效性。The electronic compass plays a key role in geomagnetic orientation which is required in unmanned airbome and vehicle navigation. Aiming at the attitude control and accuracy of vehicle navigation, an electronic compass with obliquity balance compensation is designed by integrating the characteristics of magneto-inductive sensor from PNI, MEMS accelerometer, heat meter and MSP430f1611 together. The experiment results show that the compass mentioned is small in volume, light in weight, low in power consumption and high in accuracy, thereby prove the feasibility and validity of the project.
