SPAN Configuration with NovAtel Web User Interface
Configure SPAN Manually
To enable INS as part of the SPAN system using software commands:
The SMART7 must be mounted with a clear view of the sky and tracking satellites for operation.
1. Issue the
SETINSROTATION
command, using the
RBV
parameter, to enter the Euler Angle rotation from
the IMU Body frame of the SMART7 to the Vehicle frame. See the
SETINSROTATION
command in the
Agriculture 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
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
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 SMART7 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 (
).
4.5 Real-Time Operation
SPAN operates through the OEM7 command and log interface. Refer to the
log and command details. .
Real-time operation notes:
l
By default, raw IMU data will begin to output as soon as the IMU is connected. However an initial position is
required to begin the INS alignment process. This position is typically set by GNSS. The GNSS position will
