127251 Rate of Turn
Rate of change of the Heading.
B 100 10
127257 Attitude
Provides a single transmission that describes the
position of a vessel relative to both horizontal and
vertical planes. This would typically be used for
vessel stabilization, vessel control and onboard
platform stabilization.
B 1000 1
127258 Magnetic Variation
Message for transmitting variation. The message
contains a sequence number to allow synchronization
of other messages such as Heading or Course over
Ground. The quality of service and age of service are
provided to enable recipients to determine an
appropriate level of service if multiple transmissions
exist.
1000 1
128259 Speed
Provides a single transmission that describes the
motion of a vessel.
B 1000 1
129025 Position, Rapid Update
Provides latitude and longitude referenced to
WGS84. Being defined as single frame message, as
opposed to other PGNs that include latitude and
longitude and are defined as fast or multi-packet, this
PGN lends itself to being transmitted more
frequently without using up excessive bandwidth on
the bus for the benefit of receiving equipment that
may require rapid position updates.
B 100 10
129026 COG & SOG, Rapid Update
Single frame PGN that provides Course Over
Ground (COG) and Speed Over Ground (SOG).
B 250 4
129027 Position Delta, High Precision Rapid Update
The "Position Delta, High Precision Rapid Update"
Parameter Group is intended for applications where
very high precision and very fast update rates are
needed for position data. This PGN can provide delta
position changes down to 1 mm with a delta time
period accurate to 5 msec.
B 100 10
129028 Altitude Delta, High Precision Rapid Update
The "Altitude Delta, High Precision Rapid Update"
Parameter Group is intended for applications where
very high precision and very fast update rates are
needed for altitude and course over ground data. This
PG can provide delta altitude changes down to 1
millimeter, a change in direction as small as 0.0057°,
and with a delta time period accurate to 5 msec.
B 100 10
129029 GNSS Position Data
Conveys a comprehensive set of Global Navigation
Satellite System (GNSS) parameters, including
position information.
