RNG & BRG MODE
The GPS receiver calculates the range,
bearing, cross track error (XTE) and ETA to
TO waypoint when you set a destination.
The range and bearing can be calculated by
GREAT CIRCLE (straight line between two
points) or RHUMB LINE (straight line
between two points on nautical chart)
method.
RANGE/SPEED UNIT
Selects the unit for range and speed; nm/kt,
km/ km/h, sm/ sm/h.
DEPTH UNIT
Selects unit of depth measurement among
feet, fathoms, and meters.
TEMP UNIT
Selects unit of water temperature
measurement between Celsius and
Fahrenheit.
LAT/LON DISPLAY
Displays the minutes of latitude and
longitude positions in hundredths,
thousandths or ten thousandths.
TIME DISPLAY
Selects time display format for 12 hour or 24
hour.
WAYPOINT SW
Provides automatic or manual waypoint
switching when following a route. For further
details, see page 8-5.
COURSE VECTOR
You may extend a line from the own ship
position to show ship’s course. The line can
be a vector (the length depends on the ship’s
speed) or course bar (course bar).
BEARING
A navigation device outputs both true and
magnetic bearings. A magnetic bearing is
true bearing plus (or minus) earth’s magnetic
deviation. Thus the equation for finding
magnetic bearing is;
true bearing
± x (magnetic variation)° =
magnetic bearing
You can display your ship’s course and
bearing to waypoint in true or magnetic
bearing.
