Speed Over Ground and Course Over
Ground, the information between parenthe-
ses indicate the equipment which is sending
the sentence (OSD sentence) and the type of
sensor which the info is coming from.
Manual Speed, the speed source chosen by
the operator is the manual one.
Simulated Speed, the speed simulation
has been turned on by the operator and it
overruns any other kind of speed chosen
before (differently by the manual speed, with
the simulated one, a movement of the ship
is also simulated and the Lat/Lon info are
computed).
Speed computed using a stationary target as
reference.

* WT = Water tracking log

P = Positioning system ground reference R = Radar tracking
** MANUAL DRIFT is considered: ON when MANUAL DRIFT SPEED ≠ 0;
OFF when MANUAL DRIFT SPEED = 0
For example:
•
If a serial dual axis log sensor and BT type is selected, the indication will be: SPD (BT).
•
For ship heading speed and course and speed made good, the indication will be: COG - SOG.
•
If a single axis log sensor has been selected, the text in the related row is: LOG SPD, and for
course and speed made good: SPEED – HDG.
Speed source selection
Open the speed source selection menu by pressing the “Speed Source Selection”. The main
function of this menu is to select the possible and desired own ship speed source:
•
Log Speed, it is possible to switch between ground speed and speed through water value.
