GPS Tab
The GPS tab provides a visual reference of satellite acquisition,
receiver status, and accuracy. The status information provides
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
satellites are visible to the receiver and whether or not they are
being tracked. The signal strength is shown on a bar graph for each
satellite, with the satellite number below. As the receiver locks onto
satellites, a signal strength bar appears for each satellite in view.
