Figure 36: Tait-Bryan Rotations Diagram
Yaw is the angle θ1 from the first rotation. Pitch is the angle θ2 from the second rotation
and Roll is the third rotation angle θ3, shown in the diagram above.
4.6.11.2.
IMU wrt Reference Mounting Angles:
Figure 34 shows the LVX (IMU Body Frame) and the Reference Body Fames in different
orientations. The sequence of rotations to bring the Reference Body Frame into alignment
with the IMU Body Frame will require measurement.
4.6.11.3.
Reference wrt Vehicle Mounting Angles:
If the axis of the Reference Body Frame and the Vehicle Body Frames do not align, then
the Reference Body Frame must be defined with respect to the Vehicle Body Frame by
entering Vehicle to Reference Mounting angles. These angles follow the same sequence
of rotation as described above. For example, if the x axis of the Reference Body Frame is
pointing to the right of the vehicle, the Vehicle to Reference Body Frame Mounting
Angles would be (0,0,90).
The Lever Arms and Mounting Angles are entered as shown in Figure 37.
