3.3.1 Ground / Water Stabilisation
For true vectors and trails it can be selected if the ground speed or water speed based stabilisation shall
take place. Ground stabilisation is normally used for all kind of navigational functions. Water stabilisation
is often used for anti-collision functions. In case of relative display mode, the stabilisation is not relevant.
Select
- Ground
for Bottom Track computation. The speed over ground (see COG/SOG) will be
used to determine the true vectors and trails.
- Water
for Water Track computation. The speed through water (see CTW/STW) will
be used to determine the true vectors and trails.
The position plot of the own ship and the path prediction are always ground stabilised (i.e. use the COG/
SOG vector).
