Appendix
Active Leg The segment of a route currently being traveled.
Altitude The current elevation above sea level.
BRG Bearing. The compass direction from your position
to a destination, measured to the nearest degree.
Buoy A navigation aid (usually found in marine charts) that
is floating in water. The position can vary due
to the magnitude and direction of the current.
COG Course Over Ground. The direction the receiver is
moving. COG can be reported in true or magnetic
north values.
Coordinates A unique numeric or alphanumeric description of the
position.
CTS Course to Steer. The direction you should be traveling
in order to return to the course while proceeding
towards the destination. It is a “compromise” course
bearing that projects from your current position to a
point on the courseline midway between a point
perpendicular to your position and the current leg
destination waypoint.
Datum Refers to the theoretical mathematical model of the
earth’s sea level surface. Map makers may use a
different model to chart their maps, so position
coordinates will differ from one datum to another. The
datum for the map you are using can be found in the
legend of the map. If you are unsure of which datum
to use, use WGS84.
Default The value or setting automatically chosen by the unit
unless otherwise directed. Can be changed in Setup.
DST Distance. Distance from position to destination.
ETA Estimated Time of Arrival. The estimated time of
day the leg’s destination waypoint will be reached.
