Magellan NAV 6000 88
A UTM position is described by three elements; the zone it is
in, the easting, and the northing. Eastings and northings
measure how far into a zone a position is in meters. Eastings
are an east/west measurement, and correspond roughly to lon-
gitude. Northings are a north/south measurement, and cor-
respond to latitude.
This chart shows the position of Magellan Systems described
in both Lat/Lon and UTM coo
rdinates .

Other Coordinate Systems. OSGB coordinates are similar to
UTMs, but they describe only Great Britain. They must be
used with the GBR36 datum, which also describes Great Brit-
ain. This coordinate system cannot be used in any other part
of the world. The NAV 6000 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 coor-
dinates; just be sure the map you are using uses both LAT/
LON and GBR36.)
If you select OSGB in the COORD SYS portion
of the Setup Menu be sure to change the map
datum back to the one you will be using (WGS84
is the default) when changing to another coordi-
nate system.
Irish Grid uses the Ireland datum, Swedish Grid uses the RT90
datum, Swiss Grid uses the Swiss datum, French Grid uses
the French datum, German Grid uses the German datum.
