Receiver Status and EPE

Receiver status is indicated at the top left of the

screen, with the current horizontal accuracy (estimated

position error, in feet or meters) at the top right. The

status will show one of the following conditions:

Searching— the GPS 120XL is looking for any

available satellites in view.

AutoLocate

— the GPS 120XL is initializing and

collecting new almanac data. This process can take

7.5 to 15 minutes.

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 satellites

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)— at least four satellites

with good geometry have been locked onto, 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 is

no longer tracking enough satellites for a 2D or 3D

fix.

Not Usable— the receiver is unusable, possibly

due to incorrect initialization or abnormal satellite

conditions. Turn the unit off and back on to reset.

SIM (Simulating Navigation)— the receiver is in

simulator mode.

EZinit Option Prompt

The Satellite Page also provides access to the GPS

120XL’s initialization menu, the EZinit prompt. The

EZinit prompt will appear automatically the first time

the unit is turned from the factory, after 10 minutes of

unsuccessful satellite acquisition, or if you push the

ENTER key while viewing the Satellite Page with the

unit in searching, AutoLocate, acquiring, simulator, or

poor coverage modes. (See pages 6-7 for more on

EZinit.)

A ‘POOR CVRG’ status

will appear on the Satellite

Page if the receiver has lost

the satellites required to

compute a fix. Make sure

the external antenna is not

covered and is connected to

the GPS 120XL.

REFERENCE

Receiver Status

& EZinit

If you travel more that 500

miles with the receiver off,

reinitialize the unit to your

new position by using the

EZinit feature. To access

EZinit, press ENTER from

the Satellite Page before any

satellites are acquired.
