Satellite Page

The Satellite Page displays the status of various

receiver functions. The status information will help you

understand what the GPS 120XL is doing at any given

time, and will tell you whether or not the receiver has

calculated a position fix.

Sky View and Signal Strength Bars

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 used to calculate a posi-

tion fix, and the signal quality. The sky view in the cen-

ter of the page shows a bird’s-eye view of the position of

each satellite relative to the receiver’s last known posi-

tion. The outer circle represents the horizon (north up);

the inner circle is 45º above the horizon; and the center

point is a position directly overhead.

When the receiver is looking for a particular satel-

lite, the corresponding signal strength bar will be blank

and the sky view indicator will remain highlighted in

reverse video. Once the receiver has found the satellite,

a hollow signal strength bar will appear, indicating that

the satellite has been found and the receiver is collect-

ing data from it. The satellite number in the sky view

will also change from reverse video to normal presenta-

tion. As soon as the GPS 120XL has collected the neces-

sary data to use the satellite for positioning, the hollow

bar will become solid.
