PPK workflow uses an RTK drone to collect images and positional information, paired with our high-precision smart ground control points called AeroPoints. Instead of relying on real-time exchange and risking signal loss, the actual processing of that data occurs after the drone flight is complete. PPK stands for “post-processing kinematic.”
While the drone is busy in the air, an AeroPoint on the ground also continuously records precise positional information, with more accurate triangulation. Post-flight, the GPS data from both drone and AP are matched using timestamps on the photos. The more accurate positional information from the base is used to course-correct the data.
