Use  the  “Satellite”  view  to  display  summary  data  about  the  available  satellites  in  the 
viewable sky.  

 

Parameters displayed in the Navigation view are: 

 

Satellites  –  This  column  displays  all  satellites  available  in  the  viewable  sky  by  the 
identifying number of each satellite as determined by the GPS authorities. 

 

SNR - This value indicates the carrier signal to noise ratio for the signal received by 
the individual satellite.  Typically, satellites with SNR values below 28 are not used in 
GPS fixes. 

 

Satellite Sky Map – This graphic image displays the relative position of the viewable 
satellites overhead.
