Signal Strength
The signal strength for each received channel for used satellites is illustrated graphi-
cally in the signal strength category, and represents the Carrier to Noise Ratio (C/No or
CNO) on a scale of 0 to 50, with 50 representing the optimal signal strength. Each bar
is color coded to communicate the satellite’s status per the descriptions provided in
Table 8 .
Each bar provides the satellite number and an alphabetic code that represents the
GNSS identifier. A legend is provided to the right of the bars explaining each of the iden-
tifiers. In
Figure 10 Satellite G22 provides the strongest signal (43 C/No); G225
provides the weakest signal (0 C/No).

Wireless operators often use the GNSS receivers installed in the field only for time
synchronization. They may or may not be able to use them for phase synchronization
Green Used The signal from the satellite is being used to provide
GNSS timing.
