Garmin GPS 40 - Manual (Page 13)

The sky view will help you
determine if a satellite sig-
nal is being blocked by
buildings, mountains or
other obstructions. As
satellites are locked onto,
the sky view indicators
will change from a
reverse-video highlight
to a standard display.
If you encounter difficulty
acquiring satellite signals,
try facing another direc-
tion or walk towards a
clearer view of the horizon.
The GPS 40’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 45º above the
horizon; and the center point directly overhead.
Once sufficient signals have been acquired, 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 graphic display at the top of the page
indicates your cardinal heading (only while you’re
moving) with the track and speed indicated below.
The graphic compass display is designed to show
your current track and does not serve as a true
magnetic compass while you’re standing still.
The rest of the page shows your current position
in three dimensions: latitude, longitude and alti-
tude. The GPS 40 uses this basic information to
mark exact positions as waypoints, which help
guide you from one place to another.
