Definitions and differences of GPS Carrier C/N and C/No

 

Dear Big Brother, we have a clear understanding of the GPS reception sensitivity indicators-what are the meanings of carrier C/N and C/no? What are the differences between the two.

C/NO = 10 * log (C/KTB), excluding the noise produced by the path loss and LNA routes from the day to the correlator. C/N includes all the noise.

C refers to the degree of confidence, K refers to the constant number of waves, T is the degree of attention, and B is the equivalent noise band. The calculation formula of C/N is the same as that of C/NO, but C/N contains the receiver. DB-Hz refers to the signal-to-noise ratio of a single-bit band, that is, the signal-to-noise ratio of a 1Hz band.
