Datum
Your equipment is preprogrammed with most
of the major chart systems of the world.
Although the WGS-84 system, the GPS
standard, is now widely used other categories
of charts still exist. Select the chart system
used, not the area where your boat is sailing.
Use the trackball
or ENTER knob
to select
appropriate
chart.

Position
Smoothing
When the DOP or receiving condition is
unfavorable, the GPS fix may change, even if
the vessel is dead in water. This change can
be reduced by smoothing the raw GPS fixes.
A setting between 000 to 999 is available. The
higher setting the more smoothed the raw
data, however too high a setting shows
response time to change in latitude and
longitude. This is especially noticeable at high
ship’ speeds. Increase the setting if the GPS
fix changes.

Smoothing
During position fixing, ship’s velocity (speed
and course) is directly measured by receiving
GPS satellite signals. The raw velocity data
may change randomly depending on
receiving conditions and other factors. You
can reduce this random variation by
increasing the smoothing. Like with latitude
and longitude smoothing, the higher the
speed and course smoothing the more
smoothed the raw data. If the setting is too
high, however, the response to speed and
course change slows. For no smoothing,
enter all zeros.
