(4) Setting of latitude input system
CAUTION
●
Change of the latitude input system or a large change of latitude value may cause a
large change of the true heading.
During the automatic steering, once turn the steering mode of the automatic steering
system to "MANUAL" to prevent a large course changing, and after confirming
surrounding safety of own ship, turn to "AUTO" steering again.
CAUTION
●
When an alert related to GPS (alert code "c" or "d") is generated and the true heading of
the gyrocompass has not been determined, once turn the steering mode to "MANUAL"
or "Non Follow Up", then determine the true heading because erroneous heading
information (repeater signal and serial signal) is possible to be outputted to the outside.
Refer to "3.4.5 (2) Countermeasures when GNSS communication abnormality is
generated" in Chapter 3 Operating Method, for determination method of the true
heading.
CAUTION
●
When "GYRO" is selected for the latitude input system, latitude is automatically updated
by the ship's speed and the gyrocompass true heading. (When the ship's speed input
system is "MANUAL", it is not updated automatically.) During navigation, confirm once
in 2 hours that the ship's actual latitude coincides with the indicated latitude.
