Garmin GPS 40 - Manual (Page 21)

The GPS 40 Status Page displays the status of
various receiver functions. The status information
will help you understand what the GPS is doing at
any given time.
The sky view and signal strength bars give you
an indication of what satellites are visible to the
receiver, whether or not they are being tracked,
and the signal quality. When a satellite is visible
but not being tracked, the signal strength bar will
remain blank and the sky view indicator will
remain highlighted in reverse video.
If you are losing coverage or having trouble
acquiring a position, use the sky view and signal
strength bars to guide you towards a better loca-
tion for GPS reception. If you have lost coverage
and the unit has trouble reacquiring satellites, try
shutting the unit off momentarily to reset the unit.
Receiver status is indicated at the top left of
the screen, with the current horizontal accuracy
(in feet or meters) at the top right. The status will
show one of the following conditions:
Acquiring Satellites is the first status you’ll see
in normal operation. The GPS 40 is looking for
satellites to track based on its last known p o s i t i o n .

The satellite sky view
shows a bird’s eye view
of the position of each
satellite relative to the
receiver’s last known
position.
The outer circle repre-
sents the horizon (north
up); the inner circle 45º
above the horizon; and
the center point a posi-
tion directly over your
head. Use the sky view
to help determine if
there are obstructions
shading your reception
of satellite signals.
