If SMART7-S is not installed with the front of the SMART7-S facing the direction of vehicle travel, a different set
of rotations must be entered using the
SETINSROTATION RBV
command.
Rotational Offsets – Example
Consider a SMART7-S installed as shown in the following diagram. In this installation, the factory configured
rotation does not align the IMU Body frame with the Vehicle frame. Therefore, a new IMU Body to Vehicle frame
rotation must be entered using the
SETINSROTATION RBV
command.
