Satellite Status Page

The Satellite Status Page (the last NAV page)
provides a visual reference of GPS receiver functions,
including current satellite coverage, GPS receiver
status, position accuracy, and displays your present
position (by default, in latitude and longitude) and
altitude. The Satellite Status Page also displays the cur-
rent UTC time at the bottom center of the page. The
altitude field (ALT) is user-selectable to configure the
page to your own preferences and current navigation
needs.

The Satellite Status Page is helpful in troubleshoot-
ing weak (or missing) signal levels due to poor satellite
coverage or installation problems. You may wish to
refer to this page occasionally to monitor GPS receiver
performance and establish a normal pattern for system
operation. Should problems occur at a later date, you
may find it helpful to have an established baseline
from which to compare.

Guide Addendum)
As the GPS receiver locks onto satellites, a signal
strength bar appears for each satellite in view, with the
appropriate satellite number (01-32, WAAS satel-
lites will have higher numbers) underneath each bar.
The progress of satellite acquisition is shown in three
stages:
• No signal strength bars — the receiver is looking
for the satellites indicated.
When the 500W-series unit is first powered
on, an "Acquiring" status appears at the top
of the page and no signal strength bars are
displayed.
• Hollow signal strength bars — the receiver has
found the satellite(s) and is collecting data.
• Cross-hatch cyan signal strength bars — the
receiver has found the satellite(s) but it has been
excluded by the FDE program as a faulty satellite.
• Solid cyan signal strength bars — the receiver has
collected the necessary data, but is not using the
satellite in the position solution.
• Solid green signal strength bars — the receiver
has collected the necessary data and the satellite is
being used in the position solution.
The "D" character inside the bars indicates differ-
ential corrections (e.g. WAAS) are being used for that
satellite.
