Carrier

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

Values need update for newer GNSS systems.

Carrier	Comment
0	No phase information included
1	L1 phase included
2	L2 phase included

Navigation System

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

NavSystem	Comment
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)
