Calibration and Attitude Calculation Method Based on Magnetometers

In viewthat it is difficult to obtain the fly-attitude real time because of the MEMS gyro's high load and shortage of measure range when a object rolls in high speed. A method of calibration and compensation to the magnetometer was proposed. And so was the error model. A serious of experiments were implemented based on the single-axis platform and the three-axis platform with the lab-magnetometer module and the M Ti. The experimental results indicate that this method can obtain the fly-attitude effectively and the error of attitude angles is within 5°,which could satisfy the request of measuring object attitude in high dynamic environment.
