GPS satellites are positioned throughout the sky. As soon as you turn
on your Navus, it begins acquiring satellite signals. From the sky
view area on the GPS Information page, you can see which satellites
are currently in your area; each satellite has its own number.
Sky View
Satellites
A signal strength bar appears for each satellite in view; the
satellite's number appears beneath each bar. The progress of satellite
acquisition is shown in three stages:
No signal strength bar: The GPS receiver in your Navus
is looking for the satellite(s) indicated. The corresponding
number(s) appears on the sky view.
Hollow signal strength bar: The GPS receiver has found the
satellite and is collecting data. The corresponding number(s) on
the sky view is faintly highlighted.
Solid signal strength bar: The GPS receiver has collected
the necessary data and the satellite(s) is ready for use. The
corresponding number(s) on the sky view is solidly highlighted.
Once a fix has been calculated, the Navus updates your position,

ground track, and ground speed by using the best satellites in view.

The sky view provides a "bird's eye" view of the satellites' position
bars
relative to your last known position. The outer circle represents the
horizon in all directions (with cardinal heading references). The
inner circle represents an elevation of 45° above the horizon. Any
satellite depicted near the center is directly overhead. You can set
the sky view to a "Track Up" instead of "North Up" (default setting)
orientation; this causes the top of the sky view to align to your
current track heading.
