Magellan NAV 6500/NAV 6510 100
Heading The direction in which the receiver is
moving, track or ground course, (due to
wind, current, and so forth), and may also be
different from the course.
Latitude The angular distance north or south of the
equator measured by lines encircling the
earth parallel to the equator in degrees from
0
°
to 90
°
.
LAT/LON Coordinate system using latitude and
longitude coordinates to define a position on
the earth.
Leg (Route) A segment of a route that has a starting
(FROM) waypoint and a destination (TO)
waypoint. A route may consist of 1 or more
legs. For a route that is from waypoint A to
waypoint B, waypoint B to waypoint C, and
waypoint point C to waypoint D has three
legs with the first leg being from waypoint A
to waypoint B.
Longitude The angular distance east or west of the
prime meridian (Greenwich meridian) as
measured by lines perpendicular to the
parallels and converging at the poles from 0
°
to 180
°
.
Magnetic The direction toward the north magnetic
North pole from the observer’s position.
OSGB A coordinate system describing only Great
Britain, similar to UTMs. Generally used
with GBR36 datum, which also describes
only Great Britain. This coordinate system
cannot be used in any other part of the
world. The receiver automatically selects the
GBR36 datum when the OSGB coordinate
system is selected in Setup. (While OSGB
coordinates must be used with the GBR36
datum, the GBR36 datum can be used with
LAT/LON coordinates; just be sure the map
you are using uses both LAT/LON and
GBR36.)
Position Fix Position coordinates as computed by the
receiver.
