Where there is very little texture in the surface over a large area then the PPK/RTK will reduce the risk of a photogram mismatch causing a shift on a number of overlaps, so you don't need to intensify the density of GCP in those areas. The texture problem is exacerbated in poor light (when you shouldn't be flying - but occasionally needs must!).

I do not know. They typically have a free demo period with each receiver.
We've recently been wondering the same thing (using a standard base, i.e. leica/trimble) to then post process flights. The goal being to have all photos geotagged with PPK coordinates adjusted using the on-site base, prior to then doing our regular mosiac process.
I came across this recently and it appears to be the best solution (though I have not used it):

@rick-taylor Good point- the RTK in the sUAS does not replace the need for GCPs it only reduces the number you can get away with.?ÿ DJI drones can use 3rd party base stations that can create an NTRIP mount point of their own- then the DJI control can be set up to use it like a net rover.?ÿ
