Receiver Status - Garmin Personal Navigator GPS 48 Owner's Manual & Reference

Receiver Status

Receiver status is indicated at the top left of the
page, with the current horizontal accuracy (estimated
position error, in feet or meters) at the top right. The
status will be shown as one of the following conditions:
Searching— the GPS 48 is looking for any avail-
able satellites in view.
AutoLocate— the GPS 48 is initializing and col-
lecting new almanac data. This process can take 5
minutes, depending on the satellites currently in
view.
Acquiring— the receiver is collecting data from
available satellites, but has not collected enough
data to calculate a 2D fix.
2D Nav (2D Navigation)— at least three satel-
lites with good geometry have been acquired and a
2-dimensional position fix (latitude and longitude)
is being calculated. '2D Diff' will appear when you
are receiving DGPS corrections in 2D mode.
3D Nav (3D Navigation)— at least four satel-
lites with good geometry have been acquired, and
your position is now being calculated in latitude,
longitude and altitude. '3D Diff' will appear when
you are receiving DGPS corrections in 3D mode.
Poor Cvg (Poor GPS Coverage)— the receiver
isn't tracking enough satellites for a 2D or 3D fix
due to bad satellite geometry.
Not Usable— the receiver is unusable, possibly
due to incorrect initialization or abnormal satellite
conditions. Turn the unit off and back on to reset,
and reinitialize the receiver if necessary.
Simulator— the receiver is in simulator mode.
EZinit Option Prompt
The Satellite Page also provides access to the EZ
prompt whenever a position fix has not been calculat-
ed. (The unit must be in searching, AutoLocate,
acquiring, simulator, or poor coverage mode.) This
allows you to reinitialize the unit, and is useful if you
have traveled over 500 miles with the receiver off.
(The EZ prompt will automatically appear if the
init
receiver needs to be initialized. The prompt may also
appear during normal use if the antenna is shaded or
the unit is indoors.)
REFERENCE
Receiver Status
& EZinit
The signal strength bars at
the bottom of the page will
not appear until the GPS
48 has found the satellites
indicated at the bottom of
the screen.
init
If you travel over 500
miles with the receiver
off, you may reinitialize
the unit to your new posi-
tion by using the EZinit
feature. To access EZinit
press ENTER from the
Satellite Status Page
before any satellites are
acquired.
