Transmitted messages
PG No.
(PGN) Description Level Default
Update Rate
(msec) Freq (Hz)
126992 System Time
The purpose of this PGN is twofold: To
provide a regular transmission of UTC
time and date. To provide synchronism for
measurement data. B 1000 1
127250 Vessel Heading
Heading sensor value with a flag for True or
Magnetic. If the sensor value is Magnetic,
the deviation field can be used to produce
a Magnetic heading, and the variation
field can be used to correct the Magnetic
heading to produce a True heading. B 100 10
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
