Satellite Page
The GPS 12CX’s Satellite Page displays the status
of various receiver functions. The status information
will help you understand what the GPS 12CX 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 avail-
able 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 ‘2D NAV’ or ‘3D
NAV’ in the status field). You can also set the sky view
to a track up configuration by changing the ‘orienta-
tion’ option on the Map Page. (See pg. 16 for setup
instructions.)
When the receiver is looking for a particular satel-
lite, the corresponding signal strength bar will be blank
and the sky view indicator will be highlighted. Once
the receiver has found the satellite, a strength bar will
appear indicating that the satellite has been found and
the receiver is collecting data from it. The satellite num-
ber in the sky view will no longer appear highlighted.
As soon as the GPS 12CX has collected the necessary
data to calculate a fix, the status field will indicate a 2D
or 3D status.
