not understanding the roving base + rover

As title says, I’m not understanding the <3cm accuracies when both base and rover are moving.  I understand the rover accuracy can be < 3cm relative to the base’s reported position, but with the base moving, how can we get IT’s absolute position accurate to 3 cm at the same time?

Thats only possible when the moving base, it’s at the same time connected to a static base.

Hmm.  That seems to make no logical sense whatsoever.  Then a “moving base” is just another rover?  Where’s the utility?

Yes, a “moving base” is just another rover .
The system uses 3 RTK receivers. 1 for station static and 2 for Rover. The benefit of moving base mode is that you can precisely define the direction (heading) without the need for a magnetic compass sensor. (Sometimes this is required when the magnetic field sensor cannot be used because of noise or difficult of
calibration.)
