Special Windows
Although most of the windows used in the GlobalNav 310 are self-ex-
planatory, there are several windows that have special features or can be
used in unique ways. The following section describes these windows.
Satellite Information Screen (Group A)
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 satellite in the con-
stellation has a number assigned to it, called the PRN. The bar graph is
above 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 on the left side 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 hori-
zontal and ver tical lines that pass
through the circles.
The FIX number in the lower left corner
of the screen show the quality of fix. If
the FIX is 9, then it's the best you can
get. A FIX of 1 is the worst.
