How to determine if absolute orientation of IMU + magnetometer is correct?
I'm trying to use a GPS + IMU with magnetometer to drive my robot but I've been stuck on this for a while. I'm a bit confused and I don't know how to verify if the orientation my imu is providing is correct and if the orientation in the odometry frame is correct. Are there any noobfriendly guides/tutorials on how to get those working?
What have you done so far or what is your setup?
