SMART7 with SPAN Operation
Figure 24: Top View of SMART7 on a Vehicle – SMART7 Misalignment
In a typical SMART7 installation, the slight misalignments described in the examples above are
hard to detect and difficult to measure. For this reason, it is recommended that a Body to
Vehicle Frame rotation calibration routine be used so the SPAN system can determine and com-
pensate for these angles. Refer to Body to Vehicle Frame Rotation Calibration Routine on
page 71 or Multi-Line Body to Vehicle Frame Rotation Calibration Routine on page 72 for more
information.
These parameters are estimated in the background when the system is fully converged, how-
ever it is always better to have this measured as precisely as possible before mission critical
data is collected.
Since slight variations in alignment can be introduced when the SMART7 is remounted, a
Body to Vehicle Frame calibration should be performed each time the SMART7 is remoun-
ted.
An accurate RBV is especially important if the position is being transferred to an imple-
ment.

4.4 Software Configuration

On a SPAN system, both the GNSS receiver and the IMU must be configured.
