Set Drift
Depending on the choice of sensors, the values for direction and
strength (speed) of the drift are computed by the system or they
have to be entered by the user, in order to get an accurate meas-
urement for COG and SOG. In order to enter the set and drift
manually, open the dropdown lists for SOG, click on Set Drift...
and enter the values in the appropriate fields.
Afterwards, click on Set to accept the values entered.
Manual
The actual STW of the own ship can also be entered manually. In
case a manual value is presently used, the indication of the value
is preceeded by a in the same line.
Before having changed the speed to manual mode, use the Set
Speed... function in order to enter the desired value.
Setting a manual speed value for the SOG instrument often also requires the manual Set and Drift
input, in order to correct for the set and drift created by wind and waves and the current
.
Manual speed and REF TGT speed input are only to be used as temporary solution. In
both cases it must be observed repeatedly if the values used are still valid and stable.
