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
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. B 1000 1
129033 Time & Date
Single transmission that provides UTC
time, UTC Date, and Local Offset. B 1000 1
