For GPS differential dat
a: This value is the average of the most
recent differential corrections in use. When only RTCM SC104 Type
1 corrections are used, the age is that of the most recent Type 1
correction. When RTCM SC104 Type 9 corrections are used solely, or
in combination with Type 1 corrections, the age is the average of the
most recent corrections for the satellites used. Null field when
Differential GPS is not used.
For GLONASS differential dat
a: This value is the average age of
the most recent differential corrections in use. When only RTCM
SC104 Type 31 corrections are used, the age is that of the most recent
Type 31 correction. When RTCM SC104 Type 34 corrections are
used solely, or in combination with Type 31 corrections, the age is the
average of the most recent corrections for the satellites used. Null field
when differential GLONASS is not used.
NOTE 3
HDOP calculated using all the satellites (GPS, GLONASS and any
future satellites) used in computing the solution reported in each GNS
sentence.
NOTE 4
Geoidal separation is the difference between the earth ellipsoid
surface and mean-sea-level (geoid) surface defined by the reference
datum used in the position solution, "-" = mean-sea-level surface
below ellipsoid surface. The reference datum may be specified in the
DTM sentence.
UTC of position, Latitude, Longitude and Mode indicator, are the only
fields used by the AIS.
HDT – Heading true
IMO Resolutions A.424 and A.821. Actual vessel heading in degrees
true produced by any device or system producing true heading.
All fields are used by the AIS.
OSD Own ship data
IMO Resolution A.477 and MSC 64(67), Annex 1 and Annex 3.
Heading, course, speed, set and drift summary. Useful for, but not
limited to radar/ARPA applications. OSD gives the movement vector
of the ship based on the sensors and parameters in use.
