MagnetometerRealignment.pdf

Phillip,

I just noticed that last April you asked for the above document.

Best regards,

Bill

Hi Phil,

Just to make sure we are "on the same page", the document that I sent you addresses the issue of axis misalignment between magnetometer and accelerometer/gyro (IMU) sensors that you can run into when the magnetometer is mounted physically separate from the IMU and is not aligned with the IMU. As long as there is some care in mounting the magnetometer to make sure the axes of the magnetometer are parallel with the axes of the IMU, there are no misalignment issues. If not, even a small amount of misalignment causes problems because of the large vertical component of the earth's magnetic fiels.

The document does not address magnetometer offset and calibration issues. Those topics have been well covered by others.

Best regards,

Bill
