Satellite Status
As soon as the GPS receiver in your Navus has collected the
necessary data to calculate a fix, the status field indicates a 2D or 3D
status. Satellite Status is indicated at the top left corner of the page.
The status is shown as one of the following conditions:
Searching Sky
: The GPS receiver is looking for any available
satellites in view.
AutoLocate
: The GPS receiver is initializing and collecting new
almanac data. This process can take up to five minutes, depending on
the satellites currently in view.
Acquiring Sats
: The GPS receiver is collecting data from available
satellites but has not collected enough data to calculate a position fix.
2D Navigation
: At least three satellites have been acquired with good
geometry have been locked onto; a two-dimensional position fix is
being calculated. (Reads 2D Diff Nav if WAAS-enabled)
3D Navigation
: At least four satellites with good geometry have been
locked onto; a three-dimensional position fix is being calculated.
(Reads 3D Diff Nav if WAAS-enabled)
Lost Reception
: The GPS receiver has temporarily lost satellite
reception.
Poor GPS Coverage
: The GPS receiver is not tracking enough
satellites for a 2D or 3D fix due to bad satellite geometry or a shaded
antenna (such as driving between buildings).
Not Usable
: The Navus is unusable, possibly due to incorrect
initialization or abnormal satellite conditions. Turn the unit off and
back on to reset and re-initialize the receiver.
GPS is Off
: The Navus is being used indoors and cannot be used for
navigation.
Dead Reckoning
: The Navus is not tracking enough satellites for
a 2D or 3D fix and is using Dead Reckoning. See page
for more
information.
