Description
u1
Satellite ID, see 4.1.9
FreqNr
u1
0
For GLONASS FDMA signals, this is the frequency number, with an
offset of 8. It ranges from 1 (corresponding to an actual frequency
number of -7) to 21 (corresponding to an actual frequency number
of 13). Otherwise,
FreqNr
is reserved and must be ignored by the
decoding software.
