Receiver Status

Receiver status is indicated at the top left of the

page, with the current horizontal accuracy (esti-
mated position error, in feet or meters) at the top
right. The status will be shown as one of the follow-
ing conditions:

Searching

Searching – the GPS 12CX is looking for any

available satellites in view.

AutoLocate

AutoLocate – the GPS 12CX is initializing and

collecting new almanac data. This process can take
5 minutes, depending on the satellites currently in
view.

Acquiring

Acquiring – the receiver is collecting data from

available satellites, but has not collected enough data
to calculate a 2D fix.

2D Nav (2D Navigation)

2D Nav (2D Navigation) – at least three satel-

lites with good geometry have been locked onto 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)

3D Nav (3D Navigation) – at least four satel-

lites with good geometry have been locked onto,
and your position is now being calculated in lati-
tude, longitude and altitude. ‘3D Diff’ will appear
when you are receiving DGPS corrections in 3D
mode.

Poor Cvg (Poor GPS Coverage)

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

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

Simulator – the receiver is in simulator mode.

EZinit Option Prompt

The Satellite Page also provides access to the

EZinit prompt whenever a position fix has not been
calculated. (The unit must be in searching, AutoLo-
cate, acquiring, simulator, or poor coverage mode.)
This allows you to reinitialize the unit (see Appen-
dix A), and is useful if you have traveled over 500
miles with the receiver off and must initialize your
new position.
