The purpose of this PGN is twofold: To provide a
regular transmission of UTC time and date. To provide
synchronism for measurement data.

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.

127251 Rate of Turn
Rate of change of the Heading.

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.

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.

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.

129026 COG & SOG, Rapid Update
Single frame PGN that provides Course Over
Ground (COG) and Speed Over Ground (SOG).
