10.
Slowly move the electronics bottle around in such a fashion as to position the compass in as many
possible orientations as possible for pitch, roll and heading directions.
a.
UUT in neutral position : Pitch/Roll ~0 degrees, rotate device through 360 degrees of
heading (10 times)
b.
UUT in Pitch/Roll ~-90 degrees, rotate device through 360 degrees of heading (10 times)
c.
UUT in Pitch/Roll ~+90 degrees, rotate device through 360 degrees of heading (10 times)
11.
At the serial console, execute the following commands.
stop <CR>
getCurrentCompassCalibration <CR>
12.
The compass solution will be displayed to the user as well as the number of points, magnitude of
the magnetic field at this location, and the fit error. If the solution is not viable the device should
be returned to streaming with the
start <CR>
command and steps 8 through 10 should be
repeated until the fit error is ≤ 1.0% and Points is > 100.
a.
Valid solution:
Figure 5-13: Compass Calibration Table
b.
If the solution was acceptable, Fit Error ≤ 1.0 % record and provided product engineer
along with the vehicle type. Finally, save the data into the factory calibration (level2)
portion of the device with the following command then cycle power:
setLevel2CompassCalibrationFromCurrent, factory2015 <CR>
c.
Verify Factory Compass Calibration has been set by issuing the following commands:
Stop <CR>
getLevel2CompassCalibration
13.
At this point, the SSAHRS calibration is complete. Close out of remote desktop.
