3.2.11 Stabilization
Sea Stabilization
Sea stabilization gives correct course and speed through the water.
Heading and Speed inputs from gyro compass and a single axis log (or manually set speed) provide a sea
stabilized presentation.
The entire philosophy of Collision Avoidance is based upon knowledge of the heading of other vessels in
close quater situations. Only the sea stabilized presentation display the heading of moving targets.
This presentation provides a good display for collision Avoidance.
For the sea stabilization, select "MANUAL", "LOG" or "2AXIS/WT" on subsection “8.5.3.1 Setting Own
Ship Speed Equipment”.
Ground Stabilization
Ground stabilization gives correct course and speed over the ground.
Course Over the Ground (COG) and Speed Over the Ground (SOG) are for information only.
The display can be ground stabilized by input from a position fixing equipment (GPS) or from a dual axis
log.
For the ground stabilization, select "GPS" or "2AXIS/BT" on subsection “8.5.3.1 Setting Own Ship Speed
Equipment”.
Note
● Composite mode (R+P) or optional Protter mode provides a ground stabilized presentation by input
from a position foxing equipment (GPS).
