Item	Description	Settings	Default Setting
Spd/Cse	During position fixing, ship’s velocity (speed and course)	0-999 sec	5 sec
Smoothing	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 variance by increasing the smoothing. Like with
	latitude and longitude smoothing, the higher the speed
	and course 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 zeros.
GPS Speed	Calculation of ETA is based on average ship’s speed	0-999 sec	60 sec
Averaging	over a given period. If the period is too long or too short,
	calculation error will result. Change this setting if
	calculation error occurs. The default setting is suitable for
	most conditions.
Latitude,	Offsets latitude position to further refine position	0.001’S – 9.999’N	0.0’ (no offset)
Longitude	accuracy. Use the N<− −> S soft key to switch	0.001’E – 9.999’W
Offset	coordinate.
Disable	Every GPS satellite is broadcasting abnormal satellite		None
Satellite	number(s) in its Almanac, which contains general orbital
	data about all GPS satellites, including those which are
	malfunctioning. Using this information, the GPS receiver
	automatically eliminates any malfunctioning satellite from
	the GPS satellite schedule. However, the Almanac
	sometimes may not contain this information. If you hear
	about a malfunctioning satellite from another source, you
	can disable it manually. Enter satellite number (two digits,
	max. 3 satellites) with the trackball and [ENTER] knob
	and press the ENTER soft key.
Latitude	Sets initial latitude position after cold start. Use the	—	°
			45 35.000’N
	N< − −> S soft key to switch coordinate.
Longitude	Sets initial longitude position after cold start. Use the	—	°
			125 00.000’W
	W< − −> E soft key to switch coordinate.
Antenna	Enters the height of the GPS antenna unit above sea	0-99 m	5 m
Height	surface. For further details refer to the installation
	manual.
GPS Fix	Chooses position fixing method: 2D (three satellites in	2D, 2D/3D	2D/3D
Mode	view), 2D/3D (three or four satellites in view whichever is
	greater).
Cold Start	Clears the Almanac to receive the latest Almanac.	No, Yes	No
GPS STATUS	Displays GPS satellite status display. Requires GPS Receiver GP-310/320B or GPS navigator outputting
(soft key)	the data sentence GSA or GSV. For further details see the chapter on Maintenance.
