Previously, people had to invest more than 30k of dollars to purchase professional mapping drones and place a large number of control points on the ground to get accurate, survey-grade maps. This situation remains until DJI released the Phantom 4 series of commercial drones with integrated GNSS antenna and high-definition gimbal cameras. This paper proposes a commercial drone mapping solution of Phantom PPK to significantly reduced control points, explains the workflow, testing methods and how the results support this level of drone mapping accuracy.
Hi-Target inno 1 is applied in this solution to provide stable and reliable base raw static observation data for the PPK processing. It also could work as an RTK rover to measure the checkpoints on site…Read the full article »
