For proper alignment, the GNAV540 unit must be installed in the system; the same ruling applies for an exter
magnetometer.
If the calibration process is run with the GNAV540 by itself, not installed in the field system, there will be no
corrections for the magnetism in the field system. Afterwards, when the GNAV540 unit is installed in the system
(such as a vehicle) and if magnetic fields are present in the system, errors will occur due to the magnetism of the
system.
After completing the alignment procedure, the heading accuracy should be verified with all third party systems
actively using a known reference such as a compass rose, GPS track or a calibrated compass. Heading inaccuracies
