GBS – GNSS satellite fault detection
This message is used for setting the RAIM flag in the position reports
sent by the AIS.
NOTE 1
Expected error in metres due to bias, with noise = 0.
NOTE
2
Satellite ID numbers. To avoid possible confusion caused by
repetition of satellite ID numbers when using multiple satellite
systems, the following convention has been adopted:
a)
GPS satellites are identified by their PRN numbers, which range
from 1 to 32.
b)
The WAAS system has reserved numbers 33 – 64 to identify its
satellites.
c)
The numbers 65 – 96 are reserved for GLONASS satellites.
GLONASS satellites are identified by 64+ satellite slot numbers.
The slot numbers are 1 through 24 for the full GLONASS
constellation of 24 satellites, thus giving a range of 65 through 88.
The numbers 89 through 96 are available if slot numbers above 24
are allocated to on-orbit spares.
Only Expected error in latitude and Expected error in longitude is
required and used by the AIS.
GGA – Global positioning system (GPS) fix data
Time, position and fix-related data for a GPS receiver.
NOTE 1
GPS quality indicator:
0 = fix not available or invalid
