rotation from the IMU Body frame to the Vehicle frame. See the

SETINSROTATION

com-

mand in the

OEM7 Commands and Logs Reference Manual

for more information.

Accurate knowledge of the rotational offset between the IMU Body frame and the Vehicle
frame (the RBV rotation) is critical to correctly computing an attitude solution, and is
required before a Kinematic alignment is possible.

The SETINSROTATION parameters are (where the standard deviation fields are optional):

RBV x_rotation y_rotation z_rotation [x_stdev] [y_stddev] [z_stdev]

The order of rotations is Z-X-Y. All rotations are right handed.

For an example of how to solve for the IMU Body to Vehicle frame rotation refer to

Rota-

tional Offsets

on page 70.

If the rotation between the IMU Body frame and the Vehicle frame is not precisely
known, enter an approximate rotation (to the nearest 45 degrees). The precise offset
can be estimated by carrying out the

Body to Vehicle Frame Rotation Calibration

Routine

on page 84.

SPAN Configuration with NovAtel Connect

NovAtel Connect provides a wizard that takes you through the steps required to configure a
SPAN system. For information about using the SPAN Configuration wizard in NovAtel Connect,
refer to the help file available within NovAtel Connect.

NovAtel Connect version 2.0 or greater is required for OEM7 receivers. Download
the latest NovAtel Connect software and documentation from

www.novatel.com/novatel-connect

.

SPAN Configuration with NovAtel Web User Interface

The SPAN parameters can be configured using the NovAtel Web User Interface. For information
about using the NovAtel Web User Interface, refer to the online OEM7 documentation (
