Real-Time Operation - Novatel SMART7 Installation And Operation Manual

SMART7 with SPAN Operation
For an example of how to solve for the IMU Body to Vehicle frame rotation refer to Rota-
tional Offsets on page 56.
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 71.
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
s.novatel.com/OEM7).

4.5 Real-Time Operation

SPAN operates through the OEM7 command and log interface. Refer to the
mands and Logs Reference Manual
Real-time operation notes:
By default, raw IMU data will begin to output as soon as the IMU is connected. However an
l
initial position is required to begin the INS alignment process. This position is typically set by
GNSS. The GNSS position will not be used until the FINESTEERING time status is reached.
This requires a GNSS antenna connected with a clear view of the sky. See System Start-Up
and Alignment Techniques on page 66 for more details.
The inertial solution is computed separately from the GNSS solution. The GNSS solution is
