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.
