Ok, set up RS Base on arbitrary unknown point using Average SINGLE for 2 minutes. (Did not have the manual known point at the time of point collection or a CORS NTRIP point to reference).
Collected FIXED points using RS Rover with cm accuracy between BASE and ROVER.
Obviously, all the points including base point are offset a couple of meters in every direction from actual TRUE point on the global or local grid since AVERAGE SINGLE used for Base.
Is it possible to readjust/fix or transform all these points to where they should be in relation to a KNOWN point after the fact if I have coordinate / ellipsoid / orthometric data from a known point on public record?
