Garmin GPS 120 - Manual (Page 15)

The GPS 120’s Status Page provides a visual refer­
ence of satellite acquisition and position. As the
receiver locks onto satellites, a signal strength bar
will appear for each satellite in view, with the appro­
priate satellite number (1-32) underneath each bar.
The satellite sky view shows a bird’s eye view of
the position of each satellite relative to the unit’s last
known position. The outer circle represents the
horizon (north up); the inner circle 45” above the
horizon; and the center point directly overhead.
Once sufficient information is received, the Status
Page will be replaced with the Position Page,
The Position Page shows you where you are, what
direction you’re heading and how fast you are
going. The heading display at the top of the page
indicates your cardinal heading (only while you’re
moving) with the track and speed indicated below.

The rest of the page shows your current position
in three dimensions: latitude, longitude and alti­
tude. The GPS 120 uses this basic information to
mark exact positions as waypoints, which help
guide you from one place to another
The numbers to the right of the altitude field give
a relative range for the accuracy of the altitude dis­
played. GPS altitude without differential correction
is not as accurate as horizontal position, and
fluctuations in this value are normal.
