Satellite Status Bar
As soon as the GPS receiver has collected the necessary data to
calculate a fix, the status bar indicates a position fix. The current
GPS status and the accuracy of the position fix can be found in
the satellite status bar located at the top of the page. The status bar
displays one of the following messages:
Searching for Satellites
—the GPS receiver is looking for any
available satellites in view.
Locating Satellites
—the GPS receiver is locating satellites and
determining which ones are visible at your location.
Acquiring Satellites
—the GPS receiver is collecting data from
available satellites but has not collected enough data to calculate a
position fix.
Satellite status bar
Ready to Navigate
—the Trail Guide is ready to navigate routes.
2D Navigation
—at least three satellites with good geometry have
been found; a two-dimensional position fix (latitude and longitude)
is being calculated. You might need to enter your elevation if the
receiver only has a 2D fix. Displays “2D Differential” if you are
tracking one of the WAAS satellites.
3D Navigation
—at least four satellites with good geometry have
been found; your location is now being calculated in latitude,
longitude, and elevation. Displays “3D Differential” if you are
tracking one of the WAAS satellites.
Lost Satellite 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 due to
a shaded antenna, which can be caused from very dense overhead
tress or tall buildings.
Receiver Not Usable
—the Trail Guide 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 if
necessary.
GPS is Off
—the GPS receiver has been turned off and cannot be
used for navigation.
