Satellite Status Page
The satellite status page (the fi fth NAV page) provides a visual reference of GPS
receiver functions, including current satellite coverage, GPS receiver status and position
accuracy. The satellite status page 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 will appear for each
satellite in view, with the appropriate satellite number (01-32) 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.
• Hollow signal strength bars— the receiver has found the satellite(s) and is collect-
ing data (see illustration at center left).
• Solid signal strength bars— the receiver has collected the necessary data and the
satellite(s) is ready for use (see illustration at bottom left).
• Checkered signal strength bars— Excluded Satellites (See section 10, page 163)
The sky view display (at top left corner of the page) shows which satellites are cur-
rently 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.
