What do the numbers in the Bars represent?

· Signal to Noise Ratio (SNR) -- this is how well you are receiving the signal from the satellite

What does the height of a Bar represent?

· The blue bars show which satellite is being used for the navigation solution.
· The dark shows that the satellite is being tracked, but not used for solution.

· The "key" in the lower left shows what VisualGPS View has seen (GPS, WAAS, and GLONAS).

· PRN Numbers: GPS = 1 to 32, WAAS = 33 - 64, GLONAS = 65 - 96.
