All Available Signals Tracked
There are a total of 22 signals in 6 frequency bands labeled “A” to “F”. We categorize the GNSS signals,
as shown on the right, and assign them a quality score. For example, Galileo and Beidou AltBOC
signals are assigned a quality score of 1.5 because of their wider band and higher signal quality.
This screenshot to the left shows the four super engines. Each column shows the signals that are
used for that engine.
