NOISE DENSITY RATIO (C/NO)
/No is
RECEIVED CARRIER TO
The Position/Status/Data Message outputs C/No, which can be used to determine
the relative signal levels of received satellite signals (refer to Figure below). C
the received carrier to noise density ratio. The units are dBHz, where No is the noise
density ratio received in a 1 Hz bandwidth. The plot in Figure 3.13 is linear. The
satellite signal strength is measured at the antenna input. Typically, the C/No is
between 30 and 55 dB.
