This screen displays the coordinates of the satellites available in the local
area and the corresponding signal strengths. Satellites are numbered from
0-31. The satellites that your A600 receives strong, stable signals from are
used to fix the location of the GPS receiver. These satellites are highlighted
in green. The satellites that are highlighted in red indicate that although your
A600 is receiving signals from that particular satellite, the signals received
are not used to fix the position of the GPS receiver because they could be
too unstable or weak. Satellites that are not highlighted indicate that the
GPS receiver is not receiving any signals from it.
※
Received Signal Quality
The signals received from the GPS satellites are displayed in a bar graph
next to the satellite location map showing the quality of the signal, which is
quantified. This graph is also used to show the number of satellites the GPS
receiver is receiving signals from. Green bars indicate that the signals from
that particular satellite are used to fix the position of your A600. White bars
indicate that the signals from that particular satellite are too weak or unstable
to be used to fix the position of your A600.
