Position Delta, High Precision Rapid Update
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.

Altitude Delta, High Precision Rapid Update
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 mm, a change in direction as small as 0.0057°, and with a
delta time period accurate to 5 msec.

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 positioning
error. There are three DOP parameters reported: horizontal
(HDOP), Vertical (VDOP), and time (TDOP).

GNSS Sats in View
GNSS information on current satellites in view tagged by
sequence ID. Information includes PRN, elevation, azimuth,
SNR, defines the number of satellites; defines the satellite
number and the information.

GNSS Pseudorange Noise Statistics
GNSS pseudorange measurement noise statistics can be
translated in the position domain in order to give statistical
measures of the quality of the position solution. Intended for
use with a Receiver Autonomous Integrity Monitoring (RAIM)
application.
