5. These settings will command the system
to apply external differential corrections, received in
RTCM SC-104 format, on the selected input port.
None. This setting makes the system operate in
autonomous mode, not using any differential
corrections.
SOG Smoothing The SOG Smoothing parameter allows you to adjust
the level of responsiveness of the speed over ground
(SOG) measurement, as displayed by the R5
SUPREME CDU and provided in the $GPVTG and
$GPRMC sentences. The default value is zero, and
increasing the value will increase the level of SOG
smoothing.
The setting of this parameter depends upon the
expected dynamics of the vessel. If a ship is highly
dynamic, this value should be set to a lower value
since the filtering window needs be shorter in time,
resulting in a more responsive measurement.
However, if a vessel is very large and has much more
resistance to change in its motion, this value can be
increased to reduce measurement noise. The
following formula provides some guidance on how to
set this value:
SOG smoothing = 10 / maximum acceleration (in
m/s²).
If unsure on which value to set, it's best to be
conservative and leave this parameter at the
default setting of 0.00 seconds.
COG Smoothing The COG Smoothing parameter allows you to adjust
the level of responsiveness of the course over ground
(COG) measurement, as displayed by the R5
SUPREME CDU and provided in the $GPVTG and
$GPRMC sentences. The default value is zero, and
increasing the value will increase the level of COG
smoothing.
As with the SOG smoothing parameter, the setting of
this parameter depends upon the expected dynamics
of the vessel. If a ship is highly dynamic, this value
should be set to a lower value since the filtering
window needs be shorter in time, resulting in a more
responsive measurement. However, if a vessel is very
large and has much more resistance to change in its
motion, this value can be increased to reduce
measurement noise. The following formula provides
some guidance on how to set this value initially. It is
