for the purpose of my bachelor thesis I'm currently having a focus on inertial tracking/navigation.
I'd like to determine the position of an IMU in a defined space. Therefore I'm using a ADIS16488 with 3 accelerometers, 3 gyros and 3 magnetometers.
As I'm widely unexperienced in the field of inertial navigation, I have some problems to interpret the data of the magnetometers. I totally understand the data that I get from the accelerometers and gyros but I'll need some support with the magnetometers.
I guess the magnetometer works like a compass. So it is possible to determine the orientation of my IMU from the data of the 3 magnetometers, is that correct?
But how do I have to handle that data? E.g.: If I place the IMU plane on my desk and rotate the unit around its Z-Axis (YAW) in a certain angle, how do I get the value of that angle from my magnetometer data readings?
It would be great if someone could give me some hints.
Thank you in advance.
