The GlobalNav 310 can show the posi-
tion in degrees, minutes, and thou-
sandths of a minute (36 28.700') or de-
grees, minutes, seconds, and tenths of
a second (36 28' 40.9". It can also show position in UTM’s (Universal
Transverse Mercator) projection, British, Irish, and Military Grid systems.
UTM’s are marked on USGS topo-
graphic char ts. This system divides the
Earth into 60 zones, each approximately
6 degrees wide in longitude. Their unit
of measure is in meters. For example,
30 N means that the position shown to
the left of the “N” is in grid 30, and it’s
north of the equator.
British and Irish grid systems are the
national coordinate system used only in
their respective countries.
Note: In order to use either the British or
Irish grid systems, you must be in the
U.K.
