NOTE 1
NOTE 2
1 = GPS SPS mode, fix valid
2 = differential GPS, SPS mode, fix valid
3 = GPS PPS mode, fix valid
4 = Real Time Kinematic. Satellite system used in RTK mode with
fixed integers
5 = Float RTK. Satellite system used in RTK mode with floating
integers
6 = Estimated (dead reckoning) mode
7 = Manual input mode
8 = Simulator mode
The GPS Quality Indicator shall not be a null field.
Time in seconds since last SC104 type 1 or 9 update, null field when
DGPS is not used.
Geoidal separation: the difference between the WGS-84 earth
ellipsoid surface and mean sea level (geoid) surface, " – " = mean sea
level surface below the WGS-84 ellipsoid surface.
Utc of position, Latitude, Longitude and GPS quality is the only fields
that are used by the AIS.
GLL – Geographic position – latitude/longitude
Latitude and longitude of vessel position, time of position fix and
status.
Positioning system Mode indicator:
A = Autonomous
D = Differential
E = Estimated (dead reckoning)
M = Manual input
S = Simulator
N = Data not valid
The Mode Indicator field supplements the Status field (field 6). The
Status field shall be set to V = invalid for all values of Operating
Mode except for A = Autonomous and D = Differential. The
positioning system Mode indicator and Status fields shall not be null
fields.
All fields are used by the AIS.
