Range Rings
The range rings can be used to present the distance from your vessel to other chart objects.
The range scale is set automatically by the system to suit the chart scale.

targets.
A: Heading
B: Course Over Ground (COG)
The length of the extension lines are either
set as a fixed distance, or to indicate the
distance the vessel will move in the selected
time period. If no options are turned on for
This vessel then no extension lines will be
shown for your vessel.
Your vessel heading is based on information
from the active heading sensor and COG
from active GPS sensor.
For other vessels COG data is included in the
message received from the AIS system.
