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 millimeter with a delta
time period accurate to 5
milliseconds. 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 degrees, and
with a delta time period accurate
to 5 milliseconds. B 100 10
129029 GNSS Position Data- This PGN
conveys a comprehensive set of
Global Navigation Satellite
System (GNSS) parameters,
including position information. B 1000 1
129033 Time & Date - This PGN has a
single transmission that provides:
UTC time, UTC Date and Local
Offset. B 1000 1
129538 GNSS Control Status - GNSS
common satellite receiver
parameter status. B On Request On Request
129539 GNSS DOPs - This PGN
provides a single transmission
containing GNSS status and
dilution of precision components
(DOP) that indicate the
contribution of satellite geometry
to the overall positioning error.
There are three DOP parameters
reported, horizontal (HDOP),
Vertical (VDOP) and time
(TDOP). B 1000 1
