What are magnetometyers?

Posted by Lai Bo Liang on December 20, 2012 at 9:53pm

I have a really silly question buzzing on my head and I'm kind of confuse. What are the advantages of magnetometer implementation into a UAV? I have been looking all over forums for answers but I cant seem to find any. I really need your guys help.

Thx, I would appreciate your reply

    My simple understanding is that the magnetometer is used to correct for yaw drift in the gyro (over time yaw drifts and needs 'reset' against a fixed baseline - the earths magnetic field)
