Satellite name

Char

string

The name of the L-band satellite the receiver is trying to track. There are two tracking modes:

  • In Auto mode, the receiver automatically picks a satellite to track and this field shows the name of the selected satellite.

  • In Custom mode, the first 5 characters of "Custom" is reported i.e., "Custo".

3

Satellite frequency

Char

MHz

The frequency of the tracked satellite, in MHz

4

Satellite bit rate

Char

Hz

The bit rate of the tracked satellite, in Hz

5

SNR

Float

dB-Hz

The SNR (C/No dB-Hz) value of the tracked satellite

19

Total # of viterbi symbols

Total number of viterbi symbols since the last search. When the count reaches FFFFFF00 the count resets to 0.

20

# of corrected viterbi symbols

Number of corrected viterbi symbols since the last search. This count is reset along with the number of viterbi symbols.

21
