WPT UP (Waypoint Up)
The WPT is the display mode to always orient
the WPT to the top of the screen.
When this mode is used in combination with the
course up function of the plotter, the
understandable image is available.
Relative Motion (RM) and True Motion (TM)
The relative (RM) motion mode indicates
motions of surrounding targets while fixing your
ship’s position at the center of the display.
As the own ship’s position is placed at the center
of the display, the fixed targets such as the land
move on the screen when the ship navigates.
The true (TM) motion indicates the motion of
targets with respect to the specified bearing.
Fixed targets, which do not move in any
directions, stay on the screen, and all moving
targets move on the screen.
No true motion [TM] is provided for
[H UP] mode as the constantly moving
heading is used as a reference.
The true motion [TM] is also not
provided for [WPT UP] which uses the
specified course as a reference.
Caution
In [TM] mode, entering the data of the
bearing, speed and latitude/longitude
is required.
Caution
Relative motion (RM): The own ship is fixed and
other surrounding targets move on the screen.
This is useful when monitoring the surrounding
situation based on your own ship’s position.
True motion (TM): Your ship moves
according to its speed and tidal
current on the screen.
Stationary targets are fixed on the
screen. It is useful when monitoring
your ship’s position with respect to
the fixed targets such as land.
