Investigation of accuracy of PPP and PPP-AR methods for direct georeferencing in UAV photogrammetry
Earth Science Informatics, 2022 Traditionally, photogrammetric product accuracy at cm level is obtained with Ground Control Points (GCP) in UAV photogrammetry. In recent years, UAVs equipped with Post-Processing Kinematic & Real-Time Kinematic (PPK/RTK) have become widespread. Accuracy in cm-level can be obtained with relative/differential positioning with these equipment.
