The GPSMAP 135 Sounder status page provides a visual reference of various
receiver functions, including current satellite coverage, receiver operating mode
and current receiver accuracy. The status information will give you an idea of what
the receiver is doing at any given moment.
The sky view and signal strength bars give you an indication of what satel-
lites are visible to the receiver and whether or not they are being tracked. The sig-
nal strength is shown on a bar graph for each satellite, with the satellite number
below. When a satellite is visible but not being tracked, the strength bar will not
be shown and the sky view indicator will not be highlighted.
The sky view shows a bird' s -eye view of the position of each satellite relative
to the receiver' s last known position. The outer circle represents the horizon (track
up), the inner circle 45º above the horizon, and the center point a position direct-
ly overhead. Use the sky view to determine if there are obstructions shading your
reception of GPS signals.
