4. HOW TO CONTROL CHART OBJECTS
4-7
Velocity Vectors
Ship Vectors: Show or hide own ship vector.
Target Vectors: Show or hide target vectors.
Style: Select the vector style. The [std ECDIS] vector is a speed-referenced vector
symbol. [Conventional] is a simplified symbol.
Time Increments: Check to show ticks of velocity vector. This controls both own ship
and targets ticks. If ticks are too tightly spaced, they will be automatically removed
from the display, until spacing between ticks is sufficient to distinguish them separate-
ly. This depends on display scale and speed of vessel and target.
Path Predictor: Check to show the path predictor. The path predictor is a single
dashed line originating at the CCRP and drawn at a length to represent the distance
and path own ship will travel over the ground in the user-selected time interval for own
ship speed vector.
Radar Antenna: Check to mark position of radar antenna (with "x”).
4.3.2 Tracking page
Own ship past tracks
CCRP: Check to plot own ship’s track with CCRP position as reference.
Primary: Check to plot own ship's track with position fed from sensor with highest pri-
ority.
Secondary: Check to plot own ship's track with position fed from sensor with 2nd
highest priority.
Pivot: Check to plot own ship's track with own ship’s pivot position as reference.
Style: Select time stamp position for past track (indicated by Tick or Point).
Length: Select length of past track.
Labels: Select label interval.
