I have some questions about the delta angles.
What is the difference between rotation rate and delta angle?
I think delta angle calculated by a unit-conversion from rotation rate, is that right?
Can I just accumulate delta angle to represent attitude(yaw, pitch, roll)? What problems does it cause?
If I can not calculate the attitude by the method, what is the correct way to get it?
Do you know witch IMU can provide attitude directly?
