Main Pages
If satellite reception is lost, or an insufficient number of
satellites are available, you will be alerted with a ‘Poor
Coverage’ receiver status. This may be an indication of signal
interference or objects in the way of the receiver’s antenna.
When using the built-in simulator feature, the receiver status
will remind you of this setting by showing a ‘Simulating Nav’
status. Keep in mind the simulator feature should never be
used for actual navigation.
Satellite Status Page
You can use the sky view to help determine if any satellites are being blocked, and whether you
have a current position fix (indicated by ‘2D Navigation’ or ‘3D Navigation’ in the status field). You can
also set the sky view to a ‘Track Up’ configuration (instead of ‘North Up’), causing the top of the sky
view to align to your current track heading.
Receiver Status
As soon as the GPSMAP 295 has collected the necessary data to calculate a fix, the status field will
indicate a 2D or 3D status. (For ‘2D’, you may need to enter your altitude. See page 12.) Receiver status
is indicated at the top left corner of the page. The status will be shown as one of the following conditions:
Searching— the GPSMAP 295 is looking for any available satellites in view.
AutoLocate— the GPSMAP 295 is initializing and collecting new almanac data. This process can
take up to five 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 position fix.
2D Navigation— at least three satellites with good geometry have been locked onto and a two-
dimensional position fix (latitude and longitude) is being calculated. ‘2D Diff’ will appear when you
are receiving DGPS corrections with a two-dimensional position.
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 with a three-dimensional position.
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.
Simulating Nav— the receiver is in simulator mode.
