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.
