Reference position
The reference position for installation location and calculating position of the 3-axis speed is
shown in the following figure:

Height
Reference position
(0, 0)
Set the bow-stern location 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 (center of the bow)
to the position where you want to measure the ship's
speed. Normally, enter the bow position (Y1) and stern
position (Y2).
Note: In the default setting, Y1 and Y2 are entered as
follows:
• Y1: 0 m (bow position)
• Y2: 20 m (20 m backward from bow position)
Enter the appropriate value according to the ship's size,
to improve the accuracy of the 3-axis speed.
Set the height for calculating the 3-axis speed. Enter the
distance from the bottom of the ship to the position
where you want to measure the ship's speed. For exam-
ple, enter the draft value when you want to measure the
speed at draft position.
