Geodetic Datum
Note: Geodetic Datum is a reference for geodetic
survey measurements consisting of fixed latitude,
longitude and azimuth values associated with a
defined station of reference. You must have the
correct Geodetic Datum selected in your plotter so
that it will reference the correct point on the chart for
a given lat / lon. Although WGS-84 is now the world
standard, other categories of charts still exist. refer
to Appendix for a full list of geodetic datum.
See Appendix for
full list.

Smoothing
When the DOP or receiving condition is
unfavorable, the GPS fix may change greatly, even
if the vessel is not moving in water. This change can
be reduced by smoothing the raw GPS fixes. A
setting between 000 to 999 is available. The higher
the setting, the more smoothed the raw data. If the
setting is too high, the response time required to
show a change of Lat and LON will be too long. this
is especially noticeable if the vessel is moving fast.
This is especially noticeable at high ship’ speeds.
Increase the setting to increase the amount of
averaging applied to the GPS fix.
