True motion
In True motion your vessel and all moving targets move across the
Radar PPI as you travel. All stationary objects remain in a fixed
position. When the vessel’s symbol reaches 75% of the PPI radius
(A), the radar image is redrawn with the vessel symbol re-positioned
(B) 180° opposite the current heading bearing.
When True motion is selected, the True motion reset option is
available from the menu. This allows for manually resetting the radar
image and vessel symbol to its starting position.
Ú
Note: True motion is only available when the PPI is in either
North Up or Course Up orientation mode.
Offsetting the PPI center
You can set the antenna position origin to different location on the
radar PPI. The options described in the next sections are available.
Ú
Note: Offsetting the PPI center is allowed only in Relative
motion.
PPI center: Center PPI center: Look Ahead PPI Center: Offset
You return the antenna center to PPI center by using the offset
