How does one log kinematic data on an R8GNSS receiver for post-processed kinematic work? Is it just static data but the receiver is moving, or is there a setting that must be made in the configure firmware software?
If one has logged kinematic data, can it be exported to simple rinex using Trimble's Rinex Converter?
That depends on the software in your data collector
The answer will be found in the documentation for the software running on your data collector. Most likely Trimble Survey Controller, Trimble Survey Pro, or Trimble Access. Look up "PPK Survey" or something to that effect.
In Trimble Survey Controller, you would make a survey style with the survey type set to "PP kinematic".
Simple RINEX seems to be best suited for one point per file. Since a PPK data set can include both moving segments (continuous topo) and discrete points (topo point), it is a lot more complicated and chances of success are much smaller.
A quick search found this documentation from UNAVCO on PPK surveying. That should get you started.

just your base to collect static data and rover to collect kinematic data. look for the setting in your unit - mode that has static option then toggle it to kinematic mode. make sure the collect rates are the same for the 2units. usually i set it to 1second rate.
for processing just set the kinematic data in your software to kinematic and process away. instead of getting 2points you will get points for every second of data.

Thank you. R8 has no toggle, and I guess the secret is buried in the manual.

I've never tried a PPK session with the rover as the logging device. I've always used the collector.
The option is there to use the rover under survey styles, you would get a number of points without being able to control the descriptor or any start/stop events, which is usually important during a PPK topo. And I can't see how you would ever know if it fixed or lost initialization.
I set up the base to collect at 5 second intervals, some people use a one second interval at the base and 5 seconds at the rover or one second at the rover. For me one second at the rover generates too many points. 5 seconds works best for me during a topo.
I also use PPK to locate points when there is no radio coverage. Rather than move the base to collect two points over a large ridge, just go to PPK, fix, set on the point and run a session, I will usually give it at least two minutes and then check through them with a shorter session. There have been times when the base and rover will not process but a CORS or my base at the office will process the PPK session.
It's important that the base and rover are synced, the base can collect at a faster rate than the rover as long as each rover time has a corresponding base event.

i think even if you set it to static then move the rover it would collect the data too. you then change static to kinematic in your pp software.

Thanks to everyone for the help. Turns out my TDS Survey Pro will allow me to set it for kinematic data collection. Am going to try the static thing PP as kinematic as well.
