2. NAVIGATION DATA DISPLAY
2-2
2.1.1 Description of indications
Descriptions in clockwise order from top-left corner.
POSN Latitude and longitude position of your ship, input by a position-fixing equipment
(GPS, etc.).
Time Time, input by a position-fixing equipment, is available in UTC or local time, selectable
from the menu. The time format is shown before the time, "UTC" for Universal Coor-
dinated Time, or "TIME" for local time. Daylight savings time can be activated and de-
activated from the menu.
Tracking
monitor Show the history of the tracking mode in the last three minutes. See section 1.5.
Tracking
mode Show the current tracking mode: Ground, Water, or Auto. See section 1.5.
ROT Source of ROT (Rate of Turn) and ROT value. The source of ROT can be selected
from the menu. See section 2.2.7.
GPS SOG GPS-measured speed over the ground. When the GPS signal is lost, “--.-” appears.
GPS COG GPS-measured course over the ground.When the GPS signal is lost, “---.-” appears.
DPTH Depth can be shown from the transducer or from the keel ( fed from external source) ,
selectable from the menu.
Note: The ultrasound beam is injected into water at an angle. The returning echo from
a bottom arrives at an angle to the transducer and is converted into a downward-mea-
sured depth. The depth measured to a flat bottom meets the accuracy denoted in the
specifications, however the depth to a sloping bottom is not the “true” depth.
DRIFT The drift angle. The drift angle is shown on the 3-axis speed display with a brown tri-
angle.
TRIP DIST Trip distance indication.
TOTAL DIST Total distance run indication. You can reset and adjust the indication from the menu.
Wind Wind reference, speed and angle, input by a wind-measuring device. The wind angle
is shown on the 3-axis speed display with a purple triangle. Wind reference (True,
Theoretical or Relative) and wind averaging time can be set on the menu.
Current Current (tide) speed and direction. The direction of the current is shown in the 3-axis
speed display with a blue triangle. This graphic can show the direction the current is
flowing from, or the direction the current is flowing to. The blue triangle is inside the
3-axis speed display when the direction is “flowing to”, and outside that display when
the direction is “flowing from”. You can set the indication method on the menu. See
section 2.2.4.
Doppler
SOG
(or
STW)
Doppler sonar-measured speed over the ground or speed through the water.
Doppler
COG Doppler sonar-measured course over the ground.
HDG Current heading, input by a gyrocompass. “0°” appears if there is no gyrocompass
connected.
