The GPS 120 Status Page displays the status of
various receiver funrtions. The status information
will help you understand what the GPS is doing at
any given time.
The sky view and signal strength bars give you
an indication of what satellites are visible to the
receiver, whether or not they are being tracked,
and the signal quality. When a satellite is visible
but not being tracked, the signal strength bar will
remain blank and the sky view indicator will
remain highlighted in reverse video.
Receiver status is indiated at the top left of
the screen, with the current horizontal accuracy
(in feet or meters) at the top right. The status will
show one of the following conditions:
Acquiring Satellites is the first status you’ll see
in normal operation. The GPS 120 is looking for
satellites to track based on its last known position.
2D Navigation status indicates that at least
three satellites with good geometry have been
locked onto and a 2 dimensional position fix
(latitude and longitude) is being calculated. '2D
DifT will appear when you are receiving DGPS
corrections in 2D mode.
