基于MEMS和MR传感器的嵌入式系统姿态测量

Embedded Systems Attitude Determination Based On MEMS and MR Sensors

本文介绍了一种基于新型MEMS加速度计和MR(磁阻)传感器的嵌入式姿态测量系统。通过本系统,可以获得载体的三个姿态参数:基于地球磁场的方位角,基于地球重力场的俯仰角和横滚角。

This article introduces a new method to measure the attitude of an embedded system using the newly developed MEMS accelerometer and MR sensors. It gives out the three parameters of the embedded system： the yaw angle of the body based on the magnetic field of the earth , the pitch angle and the roll angle of the system based on the gravity vector.
