Don't:
• Cover
the
antenna with your hand or other objects.
• Point
the
antenna down.
• Stand under trees or other heavy foliage.
• Stand where
the
satellite signals are being blocked
by
large obstructions (such
as
buildings, in a narrow canyon, etc.)
If
you
find
that
the
eXplorist
is
not
computing
a position,
just
move to a place
that
has
a better view
of
the
sky.

you will graphically see the satellites and
their
relative signal
strength.
You
need at least three satellites with good signal
strength (indicated
by
green bars) to compute your position. A
computed position with only three satellites is termed a
20
posi-
tion
fix. When you are
getting
a
20
position fix, your elevation is
not being computed.
To
add elevation to your position fix, you
need at least four satellites with good signal strength. Positions
that
use four or more satellites are called
30
position fixes.
• Point
the
antenna up toward the sky.
• Maintain a clear view of
the
sky.
The eXplorist
500
uses information from
the
GPS
satellites
orbiting
the
earth
to
provide you
with detailed information about your exact location. This is
the
foundation
that
your
eXplorist will use
to
provide you with
the
necessary information to arrive at your destination.

The most common use of your eXplorist will
be
to
provide you with the navigation tools
you'll need
to
arrive at your chosen destination. The
simplest
route, and the one used most
often, is a
GOTO
route. This is a route

is computed
as
a straight line from where you
are
to
where you want
to
go.
Step
One:
Compute
Your
Position
The basic operation of your eXplorist is
to
use
the
GPS
satell ites to compute your pres-
ent
position. This is done internally in
the
software of your eXplorist. The only
thing
that
you need
to
do is to give your eXplorist a clear view of
the
sky
so
that
it
can receive
the
signals from
the
satellites.
