SCX Setting
Ship dimensions, ANT/CALC-SPD position
Enter the appropriate value according to the ship’s dimensions, to improve the accuracy
of the 3-axis speed. The reference position for mounting position and calculating
position of the 3-axis speed are shown in the figure below.

Description
[Ship’s Width]
Set the ship’s width, calculated from the port-side to starboard-side
of the widest section of the vessel (Setting range: 1.0 to 999.9 m).
[Ship’s Length]
Set the ship’s length, calculated to the bow-tip to the stern, along
the center of the vessel (Setting range: 1.0 to 999.9 m).
[Ship’s Height]
Set the ship’s height, calculated to the bottom of the keel to the top
of the mast (Setting range: 1.0 to 199.9 m).
[ANT Position X0]
Set the port-starboard (Lateral) position of the SATELLITE
COMPASS™. Enter negative value for port-side, positive value for
starboard-side. The center of the vessel is “0”.
[ANT Position Y0]
Set the bow-stern (Longitudinal) position of the SATELLITE
COMPASS™. Set the distance from the bow to the stern with the
bow as 0 m.
[ANT Position Z0]
Set the height of the SATELLITE COMPASS™, from the bottom of
the ship.
[CALC-SPD-
POSN Y1 (Bow)]
Set the bow-stern position for calculating the 3-axis speed. Ship’s
speed can be measured at two locations in addition to the antenna
position. Enter the backward distance from the reference position
(Fwd Center of the bow) to the position where you want to
measure the ship’s speed. Normally, keep the default settings.
Note:
The value for [CALC-SPD-Y1] is set to 0 m as default.
[CALC-SPD-Y2] is automatically set to the ship's length(set
previously, in the same menu). For most vessels, these two
settings do not require adjustment. On large vessels, where speed
and location is required at locations other than the bow, such as for
