RTKOA/B
RTK Solution Parameters
RTK
This is the “RTK output” log, and it contains miscellaneous information regarding the RTK solution. It is based on
the matched update. Note that the length of the log messages will vary depending on the number of matched
satellites in the solution, a quantity represented by #sv in the field numbers.
