Satellite Information Screen (Group O)
This screen shows technical information about the
status of the GPS receiver. The receiver has twelve
channels. Data for each channel is shown as bar
graphs on the right side of the display. Every sat-
ellite in the constellation has a number assigned
to it, called the PRN. The bar graph is beside each
satellite’s number. The higher the bar on the graph,
the better the signal is being received from the
satellite.
Each satellite is also shown on the circular graph
at the top of the screen. This shows you not only which satellites are in
your area, but also their direction from your position, and their elevation
(distance above the horizon.) The small inner circle represents 45° above
the horizon and the large outer circle represents the horizon. A satellite is
straight above you when it is at the intersection of the horizontal and ver-
tical lines that pass through the circles.
The “N” on the left center of the screen shows the direction of north rela-
tive to the satellite graph.
The FIX number in the top left of the screen shows the quality of fix. If the
FIX is 9, then it's the best you can get. A FIX of 1 is the worst. The light
bulb in the top right corner of the screen shows when the backlight is on.
