Carrier

This data field is only useful for data streams containing GNSS measurements or corrections.

Values need update for newer GNSS systems.

CarrierComment
0 No phase information included
1 L1 phase included
2 L2 phase included

Multiple systems get joined with a + sign (e.g. GPS+GLO).

NavSystemComment
BDS Chinese BeiDou (Compass)
GAL European Galileo
GLO Russian GLONASS
GPS US NAVSTAR GPS
QZS Japanese QZSS
SBAS Augmentations system SBAS (WAAS, EGNOS, GAGAN, MSAS, SDCM)
