2.8  SATELLITE STATUS PAGE
The Satellite Status Page (the sixth NAV page) provides 
a  visual  reference  of  GPS  receiver  functions,  including 
current satellite coverage, GPS receiver status, and position 
accuracy.  The Satellite Status Page (Figure 2-46) is helpful 
in troubleshooting weak (or missing) signal levels due to 
poor satellite coverage or installation problems.

As  the  GPS  receiver  locks  onto  satellites,  a  signal 
strength  bar  appears  for  each  satellite  in  view,  with  the 
appropriate  satellite  number  (01-32)  underneath  each 
bar.  The status of satellite reception is shown as follows:
•  No signal strength bars - The receiver is looking 
for the satellites indicated.
•  Hollow signal strength bars - The receiver has 
found the satellite(s) and is collecting data (Figure 
2-47).
•  Solid signal strength bars - The receiver has 
collected the necessary data and the satellite(s) is 
ready for use.
•  Checkered signal strength bars - Excluded 
satellites (Figure 2-46).
The sky view display (at top left corner of the page) 
shows  which  satellites  are  currently  in  view  and  where 
they are.  The outer circle of the sky view represents the 
horizon (with north at top of the page), the inner circle 
45°  above  the  horizon,  and  the  center  point  directly 
overhead.
