GPS Info Satellites:
The height of the bar in the bar graph, I think, indicates signal strength.
The number under each bar, I think, indicates the number of the specific satellite.
I don't know what the colors of the bars mean.
I assume that green indicates that my GPS device has locked on to that specific satellite.
However, I have seen red bars that are higher than green bars.
And I have seen some bars that are yellow.
Does anyone know what the colors mean?
