3.8 SATELLITE STATUS PAGE
The Satellite Status Page provides a visual reference
of GPS receiver functions, including current satellite
coverage,
GPS receiver status, and position accuracy.
The Satellite Status Page (Figure 3-47) is helpful in
troubleshooting weak (or missing) signal levels due to
poor satellite coverage or installation problems.

As the GPS receiver locks onto satellites, a
signal
strength bar appears for each satellite in view, with the
appropriate satellite number (01-32) underneath each
bar. The status of satellite reception is shown as follows:
• No
signal strength bars - The receiver is looking
for the satellites indicated.
• Hollow
signal strength bars - The receiver has
found the satellite(s) and is collecting data (Figure
3-48).
• Solid
signal strength bars - The receiver has
collected the necessary data and the satellite(s) is
ready for use.
• Checkered signal strength bars - Excluded
satellites (Figure 3-47).
The
sky view display (at top left corner of the page)
shows which satellites are currently in view, and where
they are. The outer circle of the sky view represents the
horizon (with north at top of the page), the inner circle
45° above the horizon, and the center point directly
overhead.
