３． Option flag-0 setting
Various setting is prepared for adjustment of Track control. Although, these settings are usually
used in developing of interface with ECDIS, the default setting is standard in the present condition.
This flag is composed of 8 bits and the setting is done by the hexadecimal number
The contents of each bit are as follows;
<Exp.>
STW data is used
．．．0
HDG data is used
．．．0
ROT data based on COG is used.
．．．1
The corrected radius data is used in the initial rudder angle calculation at starting turn
．．．1
SOG data is used only during turn.
．．．0
The end of turn is based on COG
．．．0
SOG data is used in t
he calculation of setting ROT
．．．1
The setting ROT is collected by speed ratio in the turn
．．．0
Set [4C] as this setting, since each falgs become [01001100].
Default : [03] (refer to mark
in above table.)
[03] : The actual rate of turn is used for turning control.
[4C] : The estimated rate of turn by Kalman filter is used for turning control.
