摘要
在简单介绍了姿态角和地磁场的基础上,分析了电子罗盘工作原理,设计了基于磁阻传感器、MEMS加速度传感器及SoC(System on Chip)MCU的电子罗盘。根据其构成的主要器件,分析、补偿和计算了系统误差。该电子罗盘具有体积小、重量轻、功耗低、价格低和精度高等优点。试验结果表明其能够很好地用于微型和超小型飞行器的姿态控制与导航。
On the foundation of concise introduction for attitude angles and the earth＇s magnetic field, electronic compass principle was analyzed, and based on the magnetoresistive sensors, the MEMS accelerometer and SoC （System on Chip） MCU, the electronic compass was designed and implemented. According to its main constitution components, the system error analysis, compensation and calculation were carried out. This electronic compass is small in size, light in weight, low consume in power, low price and with the merit of high accuracy. The tested result indicates that it can be well used in MAV and subminiature flight vehicle attitude control and navigation.
