Upgrade your next mapping mission with the Phantom 4 RTK – DJI\'s most compact and accurate low altitude mapping solution. Next Generation Mapping DJI has rethought its drone technology from the ground-up revolutionizing its systems to achieve a new standard for drone accuracy – offering Phantom 4 RTK customers centimeter-accurate data while requiring fewer ground control points. Centimeter Level Positioning System A new RTK module is integrated directly into the Phantom 4 RTK providing real-time centimeter-level positioning data for improved absolute accuracy on image metadata. Sitting just beneath the RTK receiver is a redundant GNSS module installed to maintain flight stability in signal-poor regions such as dense cities. Combining both modules the Phantom 4 RTK is able to optimize flight safety while ensuring the most precise data is captured for complex surveying mapping and inspection workflows.Fit the Phantom 4 RTK to any workflow with the ability to connect this positioning system to the D-RTK 2 Mobile Station NTRIP (Network Transport of RTCM via Internet Protocol) using a 4G dongle or WiFi hotspot or store the satellite observation data to be used for Post Processed Kinematics (PPK). Precise Imaging System Capture the best image data with a 1-inch 20 megapixel CMOS sensor. The mechanical shutter makes mapping missions or regular data capture seamless as the Phantom 4 RTK can move while taking pictures without the risk of rolling shutter blur. Due to the high resolution the Phantom 4 RTK can achieve a Ground Sample Distance (GSD) of 2.74 cm at 100 meters flight altitude.To ensure each Phantom 4 RTK offers unparalleled accuracy every single camera lens goes through a rigorous calibration process where radial and tangential lens distortions are measured. The distortion parameters gathered are saved into each image\'s metadata letting post-processing software adjust uniquely for every user. Built for Surveyors Offering a range of control schemes and complimentary technologies the DJI Phantom 4 RTK is developed to provide survey-grade results with greater efficiency than ever before Access a Variety of 3rd Party Applications Pilots with experience using 3rd party apps on DJI drones can access the world\'s leading drone app ecosystem for their Phantom 4 RTK with the SDK Remote Controller. Users can plug in a compatible Android or iOS device and install any compatible DJI Mobile SDK-enabled app to harness the full power of their Phantom 4 RTK.
