The Phantom 4 RTK Quadcopter from DJI is a Phantom 4 quadcopter that is designed to deliver centimeter-level accurate mapping that can be extremely useful for surveying, construction sites, and inspections. Utilizing an RTK receiver on the top of Phantom 4, the Phantom 4 RTK can achieve 1cm+1ppm RTK horizontal and 1.5cm+1ppm RTK vertical positioning accuracy.
In addition to the RTK receiver, the Phantom 4 RTK can achieve such accuracy thanks to DJI’s TimeSync system and the gimbal camera’s calibration process. The camera is the same one that’s on a standard Phantom 4, but with the Phantom 4 RTK, each camera has its radial and tangential lens distortions measured. They are added to the metadata of all captured images, allowing for accurate post-processing that account for the distortions.
The Phantom 4 RTK can perform mapping duties in real-time and When mapping, pilots can utilize the Photogrammetry and Waypoint Flight modes in the GS RTK app. This gives mapping-specific functionality, such as selecting flight paths and directly loading KML area files. Combine it all and you have an enterprise-level mapping solution that can be used right out of the box.
