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.
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.
