Waypoint - A discrete point, stored in a navigator, located on the
surface of the earth. Normally this point will be identified by Lat/Lon
coordinates although in some systems it may be shown by T.D.'s. The
AP300DLX has the capability of storing 98 waypoints.
XTE - Cross Track Error - Used to identify a vessels position relative to
a straight line drawn between two waypoints. The amount the vessel is
off to the left or to the right of this line is known as the track. It is
normally displayed in hundredths of a nautical mile, equal to 60 ft.
UTC - Universal Time Coordinated - Transmitted from satellites to
GPS receivers as the universal time reference for the Global Positioning
System.
