Post-Processed Kinematic (PPK) stands for the post-processing of aerial photographs taken with drones with high positional accuracy. The direct processing of aerial photographs is Realtime Kin
ematic (RTK). Post-Processed Kinematic is a mapping technique based on data from the GPS system, and its geodata is accurately determined in the post-processing of aerial photographs using correction data from the Global Navigation Satellite System (GNSS). Data from base stations and position data from the drone are used as correction data.
