Item	Description	Settings
Position Smoothing	When the DOP or receiving condition is	0-999 seconds
	unfavorable, the GPS fix may change
	greatly, even if the vessel is not moving.
	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 latitude and
	longitude will be too long. This is
	especially noticeable if the vessel is
	moving fast. Increase the setting if the
	GPS fix changes randomly.
Spd/Cse Smoothing	During position fixing, ship’s velocity	0-999 seconds
	(speed and course) is directly measured
	by receiving GPS satellite signals. The raw
	velocity data may vary too much
	depending on receiving conditions and
	other factors. You can reduce this random
	variance by increasing the smoothing. The
	higher the smoothing setting, the more the
	raw data will be averaged. If this setting is
	high, the response to speed and course
	changes will slow. For no smoothing, enter
	all zeroes.
Latitude, Longitude	Offsets latitude position to further refine	0.001’S – 9.999’S
Offset	position accuracy.	0.000’N – 9.999’N
