For relative motion (RM) and true motion (TM)

Relative motion indicates the motion of surrounding targets with own ship’s position fixed at the center

of the screen.

Because own ship position is centralized, fixed targets such as the land also move on the display while

the ship is moving.

True motion indicates the motion of the target as a center of the specified bearing.

Fixed targets that do not move in any direction stay on the display as they were and actually moving

targets move on the screen.

*No true motion [TM] is available for [H UP] mode because the heading always continues to move.

Relative motion (RM): The own ship position is fixed and the other surrounding targets move on the

screen.

This is useful for monitoring the surrounding situation from the own ship’s

position as a center.

“Position” selection is effective to obtain stable trail under rough current where error of speed sensor is

large,

(9) Rel mode (Relative bearing criteria)

This is to select the signal (ship’s bearing or true) as criteria to record trails, in case trail mode is used

as “REL”.

Ship’ bearing: Trails are recorded taking the ship’s bearing as criteria.

The echo moving by own ship’s turn remains as trail.

True : This is active when such a bearing sensor as gyro, GPS compass is connected,

to record trails based on the true bearing from the bearing sensor.

The echo moving by own ship’s turn is not recorded as trail. When compared with

the ship’s bearing criteria, trail image is clearer and it is easier to see the relative position

with the other vessel.
