Garmin GPS 90 - Manual (Page 42)

The GPS 90 Status page displays the status of various
receiver functions. 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 re c e i v e r,
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.
If you are losing coverage or having trouble acquiring a
position, use the sky view and signal strength bars to ver-
ify proper antenna and receiver installation. If you have
lost coverage and the unit has trouble reacquiring satel-
lites, try shutting the unit off momentarily to reset the unit.
For more information on installation, acquiring satellites
and using the GPS 90 in other applications (hunting, fish-
ing, hiking, etc.), please see Appendix A & D.
Receiver status is indicated 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

Overview
The satellite sky view
shows a bird’s eye
view of the position of
each satellite relative

circle 45º above the

ter point a position
