Periodic/Polled
Comment
This message contains the information needed to be able to generate a
GNSS observation file.
This message contains pseudorange, Doppler, carrier phase, phase lock and signal quality
information for GNSS satellites once signals have been synchronized. This message supports
all active GNSS.
The only difference between this version of the message and the previous version (
UBX-
RXM-RAWX-DATA0
) is the addition of the version field.

s
Measurement time of week in
approximately aligned to the GPS time
system. The receiver local time of week, week
number and leap second information can be
used to translate the time to other time systems.
More information about the difference in time
systems can be found in
documentation. For a receiver operating in
GLONASS only mode, UTC time can be
determined by subtracting the leapS field from
GPS time regardless of whether the GPS leap
seconds are valid.
