FIX DATUM
[POSITION FILTER]: 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. You can choose the setting from among [Off], [Low],
[Medium] and [High]. The higher the setting, the more smoothed the raw data, howev-
er too high a setting slows response time to change in latitude and longitude. This is
especially noticeable at high ship's speeds. [Off] is the "normal" setting; increase the
setting if the GPS fix changes greatly.
[SPEED FILTER]: During position fixing, ship's velocity (speed) is directly measured
