Satellite ID
195
01 ~ 32 are for GPS; 33 ~ 64 are for WAAS (PRN minus 87); 193
~ 197 are for QZSS; 65 ~ 88 are for GLONASS (GL PRN) ; 01 ~ 36
are for GALILEO (GA PRN); 01 ~ 37 are for BDS (BD PRN). GPS,
GLONASS, GALILEO and BDS satellites are differentiated by the
GNSS system ID in table 3. Maximally 4 satellites are included in
each GSV sentence.
