Garmin GPSCOM 190 - Manual (Page 58)

Receiver status is displayed at the top left of the
screen, with the current horizontal accuracy (estimated
position error, in feet or meters) at the top right. The sta­
tus field will show one of the tollowing conditions;
Searching — the receiver is looking for any available
satellites in view.
AutoLocate — the receiver is initializing and collect­
ing new almanac data. This may take 3 to 5 minutes.
Acquiring — the receiver is collecting data from avail­
able satellites but has not collected enough data to cal­
culate a 2D fix.
2D Navigation — at least three satellites with good
geometry have been locked onto, and a 2-dimension-
al position fix (latitude and longitude) is being calcu­
lated. ‘2D Dilf’ will appear when you are receiving
DGP5 corrections in 2D mode.
3D Navigation — at least four satellites with good
geometry have been locked onto and your position is
now being calculated in latitude, longitude and alti­
tude. ‘3D Difr will appear when you are receiving
DGPS corrections in 3D mode.
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 condi­
tions. Turn the unit off and back on to reset.
Simulating Navigation — the receiver is in simula­
tor mode.
EZinit Prompt
The satellite status page also displays the EZinit
prompt whenever a position fix has not been calculated
(the unit must be in searching, AutoLocate, acquiring, or
poor coverage mode).
This prompt allows you to manually reinitialize. Its a
useful feature if you have traveled over 500 miles with the
receiver off and you know it must be initialized to your
new position (the unit wall also automatically offer the
EZinit prompt after 3-.5 minutes of unsuccessful satellite
acquisition).

The EZinit prompt will
automatically appear if the
receiver needs to be ini-

or the unit is indoors.
