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.
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
PGN 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.

GNSS Position Data
Conveys a comprehensive set of Global
Navigation Satellite System (GNSS)
parameters, including position information.
129033
Time & Date
Single transmission that provides UTC time,
UTC Date, and Local Offset.

GNSS DOPs
Provides a single transmission containing
GNSS status and dilution of precision
components (DOP) that indicate the
contribution of satellite geometry to the
overall position error. There are three DOP
parameters reported: horizontal (HDOP),
vertical (VDOP), and time (TDOP).
