Satellite Constellation and Signal 
Graph
Both the satellite constellation and the satellite signal 
graph display visible satellites and their identifying  
numbers, which are assigned by the Department of 
Defense. The satellite constellation depicts each satellite’s 
position in the sky relative to the device’s current position. 
The signal graph bars indicate the strength of each satellite 
signal. 
The icons in the satellite constellation and the lines in the 
signal graph are color-coded based on the quality of the 
data they are transmitting:
Red
 
–Indicates your GPS receiver is tracking the  
  satellite, but it is not using it to navigate.

–Indicates your GPS receiver is tracking the  
  satellite, ephemeris data is available, and the satellite is  
  being used for navigation.
Yellow
 
–Indicates your GPS receiver is tracking the  
  satellite, predicted ephemeris data is available, and the  
  satellite is being used for navigation.
Blue
 
–Indicates your receiver is tracking the satellite,  
  ephemeris data is available, the satellite is being used  
  for navigation, and the satellite has WAAS corrections
