Primary Pages
Before we start the tour, let’s briefly look at the five
primary information pages used for the GPS 12. Switch
between pages by pressing either the
Q
or
J
keys.
Satellite Page
The
Satellite Page
shows satellite positions and
signal strength. Satellite positions are displayed using
two circles and a center point. The outer circle shows
satellites on level with the horizon; the inner circle is
45º above the horizon; and the center point represents
satellites directly overhead. Knowing satellite positions
will show you the direction of any blocked signals.
The bottom of the page contains a row of signal
strength bars corresponding to each satellite being used.
Position Page
The
Position Page
shows you where you are, what
direction you’re heading and how fast you’re going.
The top of the page contains a compass tape which
is a graphic representation of your heading (or ‘track’).
Your track and speed are indicated immediately below.
The graphic compass tape reflects your actual
heading (track) only while you are moving.
The rest of the page shows your current position in
three dimensions: latitude, longitude, and altitude. A
trip odometer and 12/24-hour clock are also provided.
