Satellite Page - Garmin Personal Navigator GPS 48 Owner's Manual & Reference

REFERENCE

Satellite Page

The GPS 48 Satellite
Page will help you deter-
mine which satellites are
in view, and whether or
not any satellites are
being "shaded" or blocked
from receiving satellite
signals (See satellite 02
above).
By periodically monitor-
ing the signal strength
bars at the bottom of the
page and the north up
sky view, you will be able
to see how moving to
another area with a
clearer view of the sky
will improve satellite
reception and speed up
signal acquisition.

Indicator
The GPS 48' s Satellite Page displays the status of vari-
ous receiver functions. The status information will help
you understand what the GPS 48 is doing at any given
time, and will tell you whether or not the receiver has
calculated a position fix.
Sky View and Signal Strength Bars
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 used to calculate a posi-
tion fix, and the signal quality. The satellite sky view
shows a bird' s -eye-view of the position of each available
satellite relative to the unit' s last known position. The
outer circle represents the horizon (north up); the inner
circle is 45º above the horizon; and the center point is
directly overhead. You can use the sky view to help
determine if any satellites are being blocked, and
whether you have a current position fix (indicated by a
'2D NAV' or '3D NAV' in the status field). You can also
set the sky view to a track up configuration by changing
the 'orientation' option on the Map Page. (See pg. 24 for
setup instructions.)
While the receiver is looking for satellites the satellite
number will be highlighted in the sky view. When the
receiver locates and begins satellite reception, the satellite
number will no longer be highlighted and a hollow
strength indicator will be displayed at the bottom of the
page. After the receiver has gathered the satellite infor-
mation and can use the satellite for navigation the
strength indicator bar will become solid. As soon as the
GPS 48 has gathered enough satellites to calculate a posi-
tion the status field will indicate a 2D or 3D fix.
