built-in settings for the RTK rover, the RTG dynamic, and velocity smoothing. No
additional parameters are needed. When a user specifies dynamic mode as USER,

settings can accommodate.
MBRTK Output Streams
[MBRTK1B]
The message [MBRTK1B] is used to output the moving base RTK solution. Some of the data
are analogous to PVT1B data.
[PVT1B]
[RTKSTATUS1B]
This output stream contains a variety of information about the RTK navigation process.
