Hello, so I have for mapped over certain areas using the P4 RTK and a local CORS network in the area but processing has always produced an orthomosaic still a few meters away. I have had to rely on GCPs to correct the orthomosaic.

Any tips on how to eliminate the need for GCPs to correct the orthomosaic or is it that the P4 RTK still needs GCPs?
